# FEM Analysis on Mixed-Mode Fracture of CSM-GRP

• Publish Date: 1986-08-15
• An FEM analysis for studying mized-mode fracture problem of chopped strand mat glass fibre reinforced polyester laminate was presented, The analysis was formulated on the basis of 8-node quadrilateral isoparametric element, The collapsed triangular quarter-point singular elements were used for calculating stress intensity factors K and K. The crank propagation process was computed by implementing constraint release technique, Three different approaches to the solution of stress intensity factors K and K were compared, The effect of constraint condition imposed upon the displacement of the three collapsed nodes of the crack tip elements on the K and K results was evaluated, The mixed-mode critical stiress intensity factors KⅠC and KⅡC were estimated for CSM-GRP through the consideration of K and K calculated and the measured failure load and critical crack length in the experiment.
