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。
Many scholars have done extensive research on spacial frame optimization design . but these studies are almost based on the theory of limited flexibility in small deformation linear elasticity theory , without considering the structure of the nonlinear element 对于空间刚架结构形状优化问题,许多学者都进行了广泛的研究,但研究内容几乎都是基于小变形线弹性理论的有限元法,而未考虑结构的非线性因素。
Under this background , in this paper , a relationship between shear strength and shear wave velocity is built to estimate the characteristics of foundation soil with amount . the relationship is based on the non - linear elasticity of foundation soil and the theory of mohr - couloumb strength 在此背景下,本文寻找适合于软粘土地基的剪切波速度跟抗剪强度的关系式,该关系式是建立在土的非线性弹性模型和土的莫尔?库仑强度理论的基础上的。
In the current criteria , the principal parameters are given from linear elasticity analysis . the effects of cumulation in elasto - plastic working stage is hardly analysis . the stiffness calculation of current eccentric compression member is not specialy stipulated , with the result that the calculation of internal forces are crude 指出《规范》公式中的主要参数均基于线性(弹性工作阶段)分析,对结构实际工作阶段(包括弹塑性、塑性工作阶段)由于损伤累积而引起结构性能的变化涉及较少,对常见的偏压构件的刚度计算也未作专门规定,这使得以往内力计算较为粗糙。
The poroelastic modulus could describe pore effect on elastic behavior of porous media such as rocks . from this , gassmann equation which was widely used in seismic exploration and petroleum logging was deduced . this equation was based on linear elasticity assumption and could be used only within low frequency 孔隙弹性模量描述了孔隙对岩石等多孔材料的弹性性质的影响,利用其可导出在地震勘探和石油测井界应用很广的gassamann ,该方程建立在线性弹性假设之上并仅限于低频范围。
And under the three load cases , the critical load of the cable - stayed arch bridge taking into account double nonlinearity is much smaller than taking into account linear elasticity or geometrical nonlinearity . therefore if we want to estimate the limit bearing capacity exactly , the double nonlinearity must be considered 在三种加载工况作用下,考虑双重非线性的临界荷载远小于线弹性和仅考虑几何非线性临界荷载。因此,采用线弹性和仅考虑几何非线性方法均会过高地估计结构的极限承载力,要准确评估出结构的极限承载力必须考虑双重非线性。
