Damage mechanics of composite laminates subjected to cyclic flexual load

Composite laminates are one of the advanced materials were faced problems to analysis mechanism of damage. The purpose of this study is to develop and validate damage mechanics model for composite laminate's failure and to establish the mechanics of carbon fiber reinforce polymer (CFRP) composi...
