Analysis of micro-defects in bonding of composites in metallic structures

Resumo

Validation of a non-destructive procedure used in high-performance industries for micro-defects detection inside a composite repair, with a Finite Element Method (FEM) simulation using a cohesive law. For an experimental approach, a 3D vibrometer is used to scan the composite repair and detect possible debondings. Numerical results present good agreement with the performed experiments.
