Numerical and Experimental Analysis of Compression Plate with Cut-Out

A buckling and post{buckling behavior analysis of thin-walled composite plate under a compressive force is presented. The plate with central notch was made of a carbonepoxy composite - a laminate consisting of eight symmetrically oriented plies. The one layer arrangement was taken into consideration. The main objective of the study was to investigate the behavior of the considered plate under quasi-static compression. A numerical analysis was conducted with the Abaqus commercial FEM software package. The experimental test was performed under standard conditions on a universal Zwick/Roell Z050 testing machine. The results obtained in the numerical methods are compared to these obtained experimentally. The experimental results were then used to develop new FEM models that allowed one to describe the post{buckling behavior and to estimate the ultimate load-carrying capacity of the composite plates under investigation.
