A boundary element - free method for linear elasticity 彈性力學的一種邊界無單元法
Non linear elasticity 非線性彈性學
First , mathematical expressions for hoop strain based on linear elasticity theory and deformation plasticity theory , and thus diametral strain is derived 模型推導過程是:首先根據(jù)線性彈性理論和變形塑性理論推導出周向應變的數(shù)學表達式,進而導出徑向應變。
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 利用這個速度場,通過構(gòu)建該區(qū)二維有限元模型,結(jié)合最優(yōu)化原理,反演區(qū)域分段邊界位移。
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 模型中考慮了土和襯砌、土和樁體之間的接觸面作用,采用mohr - coulomb彈塑性本構(gòu)模型進行計算分析。
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.
