Non linear elasticity 非線性彈性學(xué)
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(dǎo)過程是:首先根據(jù)線性彈性理論和變形塑性理論推導(dǎo)出周向應(yīng)變的數(shù)學(xué)表達(dá)式,進(jìn)而導(dǎo)出徑向應(yīng)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(jìn)行計算分析。
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 對于空間剛架結(jié)構(gòu)形狀優(yōu)化問題,許多學(xué)者都進(jìn)行了廣泛的研究,但研究內(nèi)容幾乎都是基于小變形線彈性理論的有限元法,而未考慮結(jié)構(gòu)的非線性因素。
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,本文尋找適合于軟粘土地基的剪切波速度跟抗剪強(qiáng)度的關(guān)系式,該關(guān)系式是建立在土的非線性彈性模型和土的莫爾?庫侖強(qiáng)度理論的基礎(chǔ)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《規(guī)范》公式中的主要參數(shù)均基于線性(彈性工作階段)分析,對結(jié)構(gòu)實(shí)際工作階段(包括彈塑性、塑性工作階段)由于損傷累積而引起結(jié)構(gòu)性能的變化涉及較少,對常見的偏壓構(gòu)件的剛度計算也未作專門規(guī)定,這使得以往內(nèi)力計算較為粗糙。
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 孔隙彈性模量描述了孔隙對巖石等多孔材料的彈性性質(zhì)的影響,利用其可導(dǎo)出在地震勘探和石油測井界應(yīng)用很廣的gassamann ,該方程建立在線性彈性假設(shè)之上并僅限于低頻范圍。
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 在三種加載工況作用下,考慮雙重非線性的臨界荷載遠(yuǎn)小于線彈性和僅考慮幾何非線性臨界荷載。因此,采用線彈性和僅考慮幾何非線性方法均會過高地估計結(jié)構(gòu)的極限承載力,要準(zhǔn)確評估出結(jié)構(gòu)的極限承載力必須考慮雙重非線性。
