Abstract
This paper is to investigate the failure process and pin-bearing strength of laminated composites under different temperatures. An incremental finite element code, based on the updated Lagrangian approach, was developed for determining the strains dis tribution of laminates under the consideration of the temperature dependent material prop erties. The quadratic failure criterion is adopted for failure predictions. Numerical results include the failure process, failure mode and ultimate bearing strength for two differ ent laminates, S-500 glass/polyester and graphite/epoxy, with three different lay-ups, [0°/45°/90°/-45°]s, [0° 2/ ±45°]s and [90°2/ ±45°]s, as well as with different end distances (e = d-4 d) and widths (W = 1.5 d-6 d). In order to verify the accuracy of the numerical calculations, the bearing strength model test is also made for understanding the effect of temperature on the failure behavior of the laminated composites with pin-loaded hole.
