Engineering Services

MultiFat provides high-level engineering consulting services in the field of fatigue, damage tolerance and structural integrity, supporting OEMs and engineering companies throughout the product lifecycle, from early design phases to certification and in-service assessments.

Fatigue & Damage Tolerance Engineering

  • Fatigue life assessments based on FEM and stress analysis
  • Low-cycle and high-cycle fatigue
  • Multiaxial and vibration fatigue
  • Fretting, contact and surface fatigue
  • Fatigue of joints: bolted, riveted and welded connections
  • Design against fatigue and durability-driven design support

Aerospace Certification Support

  • Aerospace Fatigue & Damage Tolerance certification activities
  • Preparation and review of F&DT certification reports
  • Support to CS-23, CS-25 and CS-27 compliance demonstrations
  • Damage tolerance analysis, crack propagation and fracture mechanics
  • Definition of inspection thresholds and repeated inspection intervals
  • Aircraft retirement lives and in-service fatigue assessments

Loads, Testing and Probabilistic Approaches

  • Definition and evaluation of fatigue loads and spectra
  • Preparation, development and post-processing of fatigue test campaigns
  • Probabilistic fatigue, scatter analysis, reliability and safety factors
  • Stress-strength methods and statistical post-processing of test results

Structural Analysis

  • FEM-based and hand-calculation stress analysis
  • Linear and non-linear structural assessments
  • Support to design optimization from a structural integrity perspective

Training & Knowledge Transfer

  • Training sessions for engineers in the field of fatigue and durability
  • Tailored courses focused on practical applications and certification needs

Engineering Tools

To support its consulting activities, MultiFat has developed proprietary analysis tools, including multiaxial fatigue software frameworks used internally to ensure robustness, consistency and traceability in complex fatigue assessments.

These tools are an engineering asset, complementing expertise and experience, not a commercial product focus.
