...失效(Failure by Creep)： 在一定温度和应力下，应变随着时间的增加而增加，最终 导致构件失效 松弛失效(Failure by Relaxation)： 在一定温度下，应变保持不变，应力随着时间增加而降低, 从而导致构件失效 极限应力-材料破坏时的应力：σ s 、σ 0.2 、σ b ...
In order tosolve the failureof the structural index reduction algorithms in a few cases, another algorithm which is called combinatorialrelaxation algorithm is analyzed andstudied.
