The work stays close to the hardware. Advice is grounded in mechanics, analysis, test evidence, material behavior, manufacturing condition, mission requirements, and the actual engineering decision facing the client—not in generic management consulting. [Request a Technical Discussion](https://www.fidelisaerospace.com/technical-discussion?hsLang=en) ## When consulting and advisory support is the right fit - A fatigue or fracture problem is not yet well defined and the team needs help determining the governing engineering question. - A program needs an independent perspective before test, qualification, flight, reuse, customer submittal, or another consequential decision. - A crack, unexpected failure, manufacturing defect, test discrepancy, or nonconformance requires experienced fatigue or fracture judgment. - Several technically reasonable analytical approaches exist and the team needs a defensible basis for choosing one. - A fatigue-life, crack-growth, or fracture assessment needs review before significant program decisions are made. - The available analysis, test, material, and manufacturing evidence does not tell a consistent story. - A small or growing space hardware team needs senior fatigue or fracture expertise for a defined problem without adding a permanent specialist. - A program needs help determining what additional analysis, testing, material data, or technical evidence would most effectively reduce uncertainty. ## Consulting and advisory capabilities ### Independent Technical Review Review client-generated fatigue analysis, fracture mechanics, crack-growth calculations, supporting stress or finite element analysis, test evidence, material data, assumptions, and conclusions from an independent senior perspective. The review is scoped around the engineering decision rather than a generic checklist. [Explore Independent Technical Review](https://www.fidelisaerospace.com/consulting/independent-technical-review?hsLang=en) ### Fatigue and fracture analysis strategy Define the engineering question, applicable requirements, analytical approach, required inputs, model fidelity, material data needs, verification strategy, important sensitivities, and decision criteria before detailed analysis begins. The objective is to establish the simplest technically defensible path capable of answering the question. ### Failure, crack, defect, and anomaly assessment Help determine what an unexpected crack, failure, manufacturing defect, test discrepancy, or nonconformance means for the hardware. Support development of credible technical hypotheses, identify the fatigue or fracture mechanisms that should be considered, determine what additional evidence is needed, and establish an appropriate analysis or test path. ### Structural-life advisory Support decisions involving fatigue life, mission life, repeated use, crack growth, assumed flaws, residual strength, or other questions about how long critical hardware can perform its intended function. Advisory support may integrate fatigue analysis, fracture mechanics, supporting stress analysis, material behavior, test evidence, and manufacturing information. ### Spaceflight fracture-control advisory Provide fatigue and fracture mechanics expertise supporting broader spaceflight fracture-control activities. Support may include analytical strategy, assumed initial flaw considerations, crack-growth methodology, critical flaw assessment, residual-strength reasoning, review of fracture mechanics evidence, and identification of additional analysis or material data needed to support the program. Fidelis focuses on the analytical mechanics and technical decision-making rather than nondestructive inspection services or inspection-program management. ### Test and qualification advisory Support fatigue and fracture aspects of test planning, pre-test predictions, expected critical locations, loading strategy, instrumentation considerations, expected life or fracture behavior, discrepancy assessment, and analysis-test correlation within the client-controlled test or qualification program. ### Technical leadership and capability support Provide defined-period senior technical guidance to analysts, designers, and engineering leads working through difficult fatigue, fracture mechanics, crack-growth, or structural-life problems. Support may include method selection, assumption review, analysis planning, mentoring, calculation review, and technical decision support. This is specialist advisory support rather than general engineering staff augmentation. ## Advisory work remains tied to the hardware decision Fatigue and fracture consulting should not become abstract strategy detached from engineering evidence. Fidelis begins with the hardware, loading environment, mission or service-life requirement, material and manufacturing condition, available analysis and test evidence, uncertainty, and the decision that must be made. The objective is to: - Clarify the governing technical question. - Identify the mechanisms that matter. - Separate established evidence from assumptions. - Determine which uncertainties can materially affect the conclusion. - Identify the analysis, testing, or data needed to resolve those uncertainties. - Establish a technically defensible path to the next engineering decision. ### Information commonly needed - A non-sensitive description of the hardware, configuration, mission, and engineering decision. - Relevant fatigue or fracture requirements and acceptance criteria. - Loads, mission spectra, operating cycles, stress or strain results, and supporting structural analysis. - Fatigue, fracture toughness, and crack-growth material data. - Manufacturing-process information and defect characterization where relevant. - Existing calculations, finite element models, test results, fracture surfaces, or other technical evidence. - Known assumptions, open questions, competing interpretations, and areas of uncertainty. - Program stage, schedule constraints, and the decision or review path the advisory work must support. ### Potential outputs Depending on scope, consulting and advisory engagements may produce: - Independent technical-review findings. - Marked-up calculations, models, or reports. - Fatigue or fracture analysis plans. - Crack-growth or fracture-mechanics strategy. - Technical memoranda. - Assumption and uncertainty registers. - Sensitivity recommendations. - Recommended verification or test activities. - Analysis-test correlation recommendations. - Failure or anomaly technical hypotheses. - Recommended next technical actions. - Meeting or design-review support. - Independent written technical opinions. These are possible outputs of a custom engagement rather than fixed consulting packages. ## Consulting versus analysis services An analysis service is generally centered on performing a defined technical task such as a fatigue-life calculation, fracture mechanics assessment, crack-growth prediction, or critical-flaw evaluation. Consulting and advisory support is more appropriate when the problem itself must first be framed, several forms of evidence must be reconciled, another team's work requires independent review, or experienced technical judgment is needed before deciding what analysis, testing, or hardware action should happen next. Some engagements naturally include both. ### Need an independent fatigue or fracture perspective before the next decision? Describe the hardware, technical concern, available evidence, uncertainty, and decision the team is facing. A focused technical discussion can determine whether an advisory engagement is appropriate and what information would be most useful first.

An analysis service is generally centered on a defined calculation, model, life assessment, crack-growth prediction, or technical report. Consulting and advisory support is most useful when the problem must first be framed, several evidence streams must be reconciled, another team's work must be reviewed, or senior technical judgment is needed before the next analysis, test, or hardware action is selected. ### Can Fidelis act as an independent reviewer without re-performing the entire analysis? Yes. Review depth is established from the engineering decision, technical risk, available evidence, and requested level of independence. Some reviews can focus on governing assumptions, methods, material data, key calculations, model behavior, sensitivities, and conclusions. Others may require independent calculations or models for selected critical items. ### Can Fidelis support a failure investigation? Yes, within the fatigue and fracture mechanics scope of the practice. Fidelis can support evaluation of loading, local stress or strain, fatigue mechanisms, crack initiation and growth, fracture behavior, analytical predictions, test evidence, and technical hypotheses. Metallography, fractography laboratory work, material characterization, nondestructive inspection, chemical analysis, or other specialized disciplines may require client resources or additional specialists. ### Can Fidelis advise on spaceflight fracture-control requirements? Yes. Fidelis can provide fatigue and fracture mechanics expertise supporting a broader fracture-control effort, including analytical strategy, assumed flaws, crack-growth methods, critical flaw assessment, residual strength, material-data requirements, and independent review. Fidelis does not provide nondestructive inspection services or manage inspection programs. ### Can Fidelis help determine what analysis should be performed? Yes. One purpose of an advisory engagement is to determine what engineering question actually needs to be answered and which fatigue, fracture, supporting stress, test, or material evidence is necessary to answer it defensibly. ### Can Fidelis provide ongoing technical leadership? Yes, when the need is specifically related to fatigue, fracture mechanics, crack growth, structural life, or closely supporting technical work. The engagement should have a defined technical purpose rather than functioning as general engineering staff augmentation. ### Does advisory support replace the client's engineering or program authority? No. Fidelis provides independent engineering analysis, technical advice, and review findings. Final design authority, program decisions, certification findings, hardware acceptance, and authorized compliance determinations remain with the responsible client organization and its authorized representatives.
