Abstract:

In this paper we present FE modeling of quasi-static short beam shear test of plain woven laminated composites. Cohesive elements were used in regions where transverse cracks and multiple delaminations were expected to occur based on experimental observations. Parametric studies with various properties of the cohesive elements were conducted. Predictions of peak load and load-deflection curves including post damage regime obtained through the FE simulation were compared with representative experimental results.
