| Abstract: | A three-dimensional progressive damage model was set up for predicting the bearing performance of
thick composite laminates under tensile loading. Analyzing and simulating the fibre damage, matrix damage and delamination. The 3D model has the capability of assessing the ultimate bearing strength of joints and simulating the whole process of damage initiation, propagation and catastrophic failure of the structure. The finite element method could also be used to predict the relationship between structure design parameters and load carrying capabilities. |
