摘要
对聚合物材料ＨＩＰＳ进行了系统的变形－损伤试验研究．用提出的弹塑性损伤变量与关系分析了Ⅰ型裂纹端部的损伤场，给出了损伤场内非线性纵向应变分布与纵向应力分布．
A systematically experimental research on deformation damage of polymer material HIPS was carried out. Damage field in vicinity to mode Ⅰ crack tip was analyzed by the elasto plastic damage variable and the corresponding relation presented. The nonlinear longitudinal strain and stress distribution in the damage field was obtained. A new basis for further study stable growth of crack in damage zone is based on the damage analysis.
