聚脂基复合材料板的粘弹性损伤本构关系

Viscoelastic Damage Constitutive Relations for Polyestermatrix Composite Plate

从在不同的常应变率控制下正交铺设的玻璃纤维布／聚脂复合材料板的几项拉伸试验着手，提出了该材料粘弹性的损伤等价性原理．应用热力学的内变量的概念，在实验的基础上建立了该材料的损伤本构关系．

The equivalace principle of damage energy release rate is proposed in this paper for an orthogonal glass fibre cloth/polyester composite plate to different constant strain rate. The damage constitutive relations for it were given on the base of experiment and from using internal variables theory of thermodynanics.
