摘要

采用无损声成像实验和三维有限元分析方法研究了颗粒增强聚合物复合材料的裂纹-损伤相互作用现象。评估了损伤尺寸和损伤程度对I型应力强度因子和裂纹尖端附近局部应力场的影响,讨论了损伤和裂纹扩展行为。

Damage Characteristics Near Crack Tip for a Particulate Composite
Nondestructive acoustic imaging experiments and three dimensional finite element analyses were performed to study the crack-damage interaction phenomenon of a particle reinforced polymeric composite. Effects of damage size and degree of damage on the mode I stress intensity factor and the local stress fields near the crack tip were evaluated and the damage and crack growth behavior were discussed.
