failure strength meaning in English

破坏强度

Two kinds of mathematical models of the forklift truck in intensive test and their formulas of parameters estimation are established ; thereby the cumulative failure strength function of the forklift truck in intensive test is obtained . the author also applies the related - index - method ( rim ) to verify the analysis results
本文运用随机过程理论，根据可靠性强化试验叉车故障数据的特点，建立了可靠性强化试验叉车的可靠性数学模型，推导了其参数估计公式，从而得到了可靠性强化试验叉车的累积故障强度函数，并运用相关指数法对分析结果进行了验证。
When 0 ? ply is included and lay on the surface in a laminate , the ultimate strength is the highest ; if a laminate does not possess both 0 ? ply and 90 ply , then it shows relatively large first - ply failure strength , but the ultimate strength is much smaller than that of laminates including 0 ply
拉伸试验和有限元数值分析表明：若板内含有0 ?层，且该层位于板的表层时，则最终强度最大；若板内既无0 ?层，又无90 ?层，则初始层破坏强度较大，而最终强度远小于含有0 ?层板的最终强度。
