From the perspective of macro and micro combinations

a series of failure criterions and corresponding stiffness reduction methods for multi-failure models of warps and wefts were developed based on modified Hashin criterion. Systematic static strength analytical method for 2.5 dimensional woven complex structures was presented based on gradually damage concept. Also

the tension stress-strain curves along the warp and weft were simulated

and the fitting curves were in good agreement with the experimental results with the errors of calculated stress less than 6.5% for given strains; and for 2.5 dimensional woven connection structure simulation of compressor

gradually damage process was simulated. The result shows that main damage of the structure occurs around the chamfer of the root; specifically

matrix compress failure on the root of suction surface can cause great deformation as a major cause of the destruction of the structure.
