A boundary element - free method for linear elasticity 弹性力学的一种边界无单元法
Non linear elasticity 非线性弹性学
First , mathematical expressions for hoop strain based on linear elasticity theory and deformation plasticity theory , and thus diametral strain is derived 模型推导过程是:首先根据线性弹性理论和变形塑性理论推导出周向应变的数学表达式,进而导出径向应变。
On the basis of this velocity field and the optimization theory , the segmented displacement of the boundary of the studied area are deduced with two - dimensional finite element model of linear elasticity 利用这个速度场,通过构建该区二维有限元模型,结合最优化原理,反演区域分段边界位移。
The contact interactions between soil and lining , and between soil and pile are taken into account . the constitutive model employed is mohr - coulomb plasticity with linear elasticity assumed within the yield strength surface 模型中考虑了土和衬砌、土和桩体之间的接触面作用,采用mohr - coulomb弹塑性本构模型进行计算分析。
Linear elasticity is the mathematical study of how solid objects deform and become internally stressed due to prescribed loading conditions. Linear elasticity models materials as continua.
