Post-buckling behavior of thermoplastic matrix composite laminates subjected to pure shear

摘要

The present study focuses on the determination of the buckling load and post-buckling behavior of simply supported laminated composte rectangular panels loaded in shear. The nonlinear structural response is studied with a non-linear finite element approach. In order to determine the accuracy of the procedure, several tests have been performed comparing the finite element solutions for isotropic and laminated composte rectangular panes with existing ones, adopting different sequences of maintain and different length to width ratios. The analysis then considers the behavior of laminates produced with innovative thermoplastic matrix composites developed in the frame of a national research program.
