ENGINEERING Failure Analysis
Intec capabilities in designing, manufacturing and testing composite structures and elements give us a unique advantage when investigating failure scenarios.
Whether the failure occurs in factory or in the field, in a new or aged structure, our engineers have the tools and experience to identify and document the root cause of a failure in your product.
From failure of in-line skate fittings to disbonds in commercial transport horizontal stabilizers, Intec's investigative team can find the answers you need. Our team belongs to a closely associated network of leading industry experts in specialty areas from control to process modeling. This gives you access to the world's leading experts in composite manufacturing, structure and aging.
Intec's testing labs are often used to investigate and document failure areas. Examples of techniques used to model failure include progressive failure models such as strain softening and virtual crack closure, fracture-based hygrothermal load cycling modeling for microcracking and paint cracking, thermo stress kinetics/degradation modeling for lightning strike, Dyna-3D for modeling dynamic events including impact, and standard FEM analysis modeling for global stress state.
Some typical failure modes include:
- Adhesive or laminate contamination.
- Bearing failure and failure in joints.
- Delamination due to impacts of out-of-plane internal/external forces.
- Progressive inplane damage growth after some initiation event.
- Material degradation due to thermal, hygrothermal, uV, solvent effects.
- Microcracking and paint cracking.
- Corrosion of associated metal structures.
