Numerical Analysis of the Damage Behaviour of the Polyamide CFRP Composite Beam Laminated With Cohesive Layer

Description

Three point bending test is performed on hybrid beam using different loading condition.

For internal reinforcing layer of the beam, which dominated by fiber glass layers and the outer polyamide layer, the matrix failure index of Hashin Rotem’s failure criterion was chose While debonding between fibre glass and Polyamide layers was modeled by the cohesive zone model with the traction separation law using Qudratic stress damage criteria.
