A progressive failure analysis of all-C/SiC composite multi-bolt joints

A progressive damage model (PDM) was proposed to analyse the failure of plain-weave carbon fibre-reinforced silicon carbide (C/SiC) composite joints with C/SiC bolts, which were manufactured by the chemical vapour infiltration (CVI) technique. A bilinear constitutive model was established to describe the pseudo-plasticity of the C/SiC composites. Several failure criteria, including the maximum stress failure criterion, Tsai-Wu failure criterion,...
