Damage Theory for Polymetric Material
-
摘要: 本文研究了外界环境如载荷、温度、湿度、辐射、腐蚀介质、非相容介质等对聚合物材料变形的影响,给出了微分型和积分型损伤演化方程;讨论了非线性弹性体和非线性粘弹性损伤变形以及腐蚀损伤.给出了粘弹性损伤变分原理.Abstract: In this paper,the effects of external environment such as corrosion medium,radiation and non-consistent materials on deformation of polymers are discussed. Damage constitutive equations for non-linear elastic and non-linear viscoelastic polymers and a variational principle for viscoelastic damage are also given.
