具有初始非线性层合板的粘弹性屈曲

Viscoelastic Buckling of Composite Laminated Plates with Initial Material Nonlinear Behavier

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。

The viscoelastic creep and initial material nonlinear behavior are considered in the constitutive relation, which is concerned with the buckling of glass fiber reinforced expoxy composites laminated plates. The weighted residual method and iteration method are used in the solving process. Many significant curves and results are obtained.
