## Study of the delamination of a composite bar: Comparison between various computation methods.(English)Zbl 0708.73046

Summary: Our purpose is to compare several methods for the computation of the energy release rate. In particular, a comparison is made between a 2.5D analysis and methods based upon plate theories. Computations are made on a laminate $$[35,-35,0,90]_ s$$ exhibiting delamination with a constant depth along the specimen on the (0,90) interface.
