本文选用一种既考虑材料的蠕变特性,又考虑材料在初始状态具有非线性的本构关系,对玻璃钢复合材料层合板的屈曲问题进行了计算与分析。计算中采用了加权残值法及迭代法,由此得到了一些重要曲线及结论。
In this paper, a kind of constitutive relation considering both the creep property of material and the nonlinear state of the material in the initial state is considered in this paper. The buckling problem of FRP laminates is calculated and analyzed. Weighted weighted residuals method and iterative method are used in the calculation, and some important curves and conclusions are obtained.
