MultiFat – Fatigue & Damage Tolerance Engineering Consultancy

MultiFat is an independent engineering consultancy providing high-level expertise in fatigue, damage tolerance and structural integrity, with a strong focus on aerospace and certification-driven applications.

Founded and led by a senior aerospace engineer with more than 30 years of international experience, MultiFat supports OEMs and engineering companies in addressing complex fatigue and durability challenges, from early design phases to certification and in-service assessments.

The consultancy combines:

• deep theoretical knowledge,
• extensive hands-on industrial experience,
• and a pragmatic, certification-oriented engineering approach.

MultiFat operates as an expert boutique, offering direct access to senior-level competence, flexibility, and technical rigor.

Areas of Expertise

MultiFat provides consulting services in the following areas:

• Fatigue and Damage Tolerance of aerospace structures (fixed wing and rotorcraft)
• Aerospace F&DT certification reports (CS-23, CS-25, CS-27)
• Fatigue life evaluations based on FEM and stress analysis
• Definition and assessment of fatigue loads and spectra
• Preparation, execution and post-processing of fatigue test activities
• Vibration fatigue and random loading analysis
• Low-cycle and high-cycle fatigue
• Probabilistic fatigue, scatter, reliability and safety factors
• Damage tolerance, crack propagation and fracture mechanics
• Definition of inspection thresholds and intervals
• Aircraft retirement lives and in-service fatigue assessments
• Design against fatigue and durability-driven design support
• Fatigue of joints (bolted, riveted, welded) and fretting fatigue
• FEM-based and hand-calculation stress analysis

Engineering Tools

As part of its consulting activity, MultiFat has developed proprietary analysis tools, including a multiaxial fatigue software framework used internally to support advanced fatigue assessments.

These tools are not a commercial product focus, but an engineering asset developed to ensure robustness, consistency and traceability in real industrial applications.
