The composites damage mechanism analysing and simulation to composites random destroyed course

摘要

Analyse the destruction mechanism of the textile structure composites and provide the dynamic simulation method to destroyed course. The initial state of lattice point mechanics of the composites is satisfied certain random distribution, which can carry on random probability simulation through Monte Carlo method , it is set up adjoint mechanics balance under lattice point with destroy with lattice point spring model course invalid loaded transmission distribute the principle to come, provide the lattice point lose efficiency and destroy the condition critically. Combination of Monte Carlo method and model of lattice point inter spring can close the true destruction course of composites compared with simplicity to using finite element method.
