计算力学中的静力衰减
The Theory of Static Decay in Computational Mechanics
-
摘要: 本文在计算力学范围内证明了,平衡力系的影响,由近及远按矩阵连分式的规律衰减.该衰减往往不慢于,但并非总是不慢于指数衰减或幂次衰减.本文结果可用于估计某些简化假定在计算中引入的误差.Abstract: In this paper,a new mathematical form,matrix,continued fraction(MCF) is introduced to describe the decay of effects of an equilibrant system of forces acting on a sphere of an elastic body.By this way,the famous Saint-Venant's principle is proved often but not always valid in computational mechanics.
