The Visualization Method of Progressive Damage of Woven Composites

This work elaborates an visible progressive damage model of the woven composites. This model creates a multi-integral-point unit element, on which the integral points are arranged evenly across the unit cell element. These integral points are divided by region division sub- model, and any of these points can represent the whole properties of the geometry and material across the thickness at the position it belongs. The visible progressive damage model can calculate, record and present the regional stress, strain and damage mode of the woven composites, and obtain the sequence and damage mode of the components. The article also creates an ASCII storage method to access the damage mode of these integral points in each step, which can reduce the requirement of the computing and storage ability of the computer. © 2022 Cailiao Daobaoshe/ Materials Review.
