摘要
从损伤力学的理论观点,区别于弹塑性力学的角度,研究了超高压容器的损伤自增强,进行了超高压厚壁筒损伤自增强的应力分析,通过残余应力的计算,充分说明了利用超高压厚壁容器内壁损伤可以产生自增强的效果。这一结论为超高压厚壁容器自增强理论研究,提供了新的探讨方向。
According to the theory of damage mechanics, in a way different from e lasfic-plastic mechanics, this thesis studies vessel's self-reinforced damage me chanism under super-high temperature, anylizes thick walled vessel's residual st ress with self-reinforced damage under super-high temperature. Through the study and analysis, it concludes that by making use of the inner wall damage caused b y super -high temperature in a thick walled vessel, the self-reinforced stress i s developed. This conclusion leads to a new direction of study on self-reinforc ed damage mechansm.
