## Determination of Expression of Continuous Damage Parameter for Non-Ageing Materials Under Constant Tensije Load

• 摘要: 在不变的拉伸截荷P作用下,非老化脆性材料连续损伤参数可表示为w(P/A0)=g(P/A0)+f1(P/A0)f2(t)其中g(P/A0)表示式的确定方法已由[4]指出了,而f1(P/A0)和f2(t)表示式的确定方法迄今没有人给出过。现在本文解决了这个问题,本文指出,f1(P/A0)f2(t)=φ(P/A0)t,并且给出了确定φ(P/A0)表示式的具体方法。
