Abstract

Structural failure is initiated when a material is stressed beyond its strength limit. [cite: 2] Determination of failure loads and failure location is one of the most important problems in design structures. [cite: 3] This paper analyzed the failure of the hat-type laminated composite plate under a bending load. [cite: 4] Based on the Reissner-Mindlin plate theory and isoparametric rectangular plate elements with five degrees of freedom per node, an algorithm and Matlab code were established to compute the stresses and bending failure load of the folded composite plate according to Tsai-Wu and Maximum stresses criteria. [cite: 5] The numerical results are reliable when compared with the published results in the literature for some specific cases. [cite: 6]
