Random elasto-plastic lattice modeling of damage in fibrous materials

摘要：

　　A random elasto-plastic lattice network model is developed to simulate the damage behavior of fibrous materials.Elasto-plastic bar elements are used to construct a regular lattice network with the random element strength distributions to simulate the randomness of the continuum fibrous materials.The structural response of the elasto-plastic lattice network under displacement controlled loading is studied using finite element method.Small deformation theory is used and the modified Newton-Raphson algorithm is applied to solve the nonlinear finite element equations.The effects of correlation length of the strength distribution of bar elements on the global behaviors are studied.
