摘要:
本文把弹性力学的Betti功互换定理推广到弹塑性、粘弹塑性和弹性体运动状态,利用虚位移和虚速度的原理,导出了各种情况下的Betti广义互换方程。并以纯弯曲悬臂梁,压杆稳定和薄板振动问题为例。说明了广义互换定理的应用。
Abstract:
In this paper, Betti’s work reciprocal theorem in the field of elastic mechanics is extended to the study of elastoplasticity, visco-elastoplasticity and the motion state of elastic bodies. A generalized Betti’s reciprocal equation in various conditions i
