This study investigates the stability and failure analysis of thin-walled composite plate elements
with asymmetric configuration, subjected to axial compression. The analyzed plates were made of
carbon fiber reinforced polymer (CFRP) composite material by the autoclave technique. The scope
of the research included experimental tests on actual samples and numerical calculations with using
the finite element method in the ABAQUS® program. The experimental tests and numerical analysis
were performed until failure phenomenon. In experiments, postbuckling equilibrium paths and acoustic
emission signals were measured, which allowed a comprehensive analysis of failure for the composite
material. Numerical calculations were performed using advanced numerical damage models, which
allow, among other things, to simulate the phenomenon of loss of load carrying capacity, along with the
phenomena associated with failure. Numerical results of critical and post-critical state were compare
with experimental research showing areas prone to failure of the material.
