Numerical investigation on the variation of compressive failure mechanisms in unidirectional carbon fiber reinforced polymer

This paper presents a study on the variation of compressive failure mechanisms in carbon fiber reinforced polymer (CFRP) as well as the effects of material properties and structure parameters on the compressive strength in different failure mechanisms. A two-dimensional microscale model is developed to simulate numerically the compressive process of CFRP with local structure imperfections. The fiber kinking can be induced by either the...
