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

  • Under constant uniazial tensile load continuous damage parameter for non-ageing brittle materials may be ezpressed as
    w(P/A0)=g(P/A0)+f1(P/A0)f2(t)
    The determination of the expression for g(P/A0)had been pointed out by[4].Hut how to determine the expressions for f1(P/A0)and f2(t), the solution to this problem is not yet in sight.Now the solution to this problem is given by the present paper, This paper points out f1(P/A0) f2(t)=φ(P/A0)t and the method of the determination of the expression for φ(P/A0).
