Based on an established stochastic weighted residual method formulation , stochastic buckling of a cylinderic shell is discussed 摘要在建立隨機(jī)加權(quán)殘數(shù)法公式體系的基礎(chǔ)上,討論了圓柱殼屈曲的概率分析。
First , the penalty finite element balance equation for quasi - static problem is obtained by the application of galerkin weighted residual method and the introduction of penalty parameter 首先,采用伽遼金加權(quán)余量法推導(dǎo)有限元平衡方程,利用罰方法得到求解擬靜態(tài)問題的罰有限元公式。
Compactly supported function is used to construct the trial function , and weighted residual method with compactly supported function is employed to discretize the differential equation 無網(wǎng)格法是以一系列節(jié)點(diǎn)離散求解域,使用緊支函數(shù)構(gòu)造試函數(shù),采用加權(quán)余量法導(dǎo)出微分方程等效形式。
In terms of the weighted residual method to the springback anti - coupled equations , the springback potential energy principle and springback complementary energy principle of axisymmetric problems are established 應(yīng)用加權(quán)馀量法于該回彈反耦聯(lián)方程,建立了軸對(duì)稱問題的回彈勢能原理和回彈馀能原理。
Then the penalty finite element formula can be derived through galerkin weighted residual method . to test the model , the paper calculate a cantilever sample and a four point bending beam under near static load and sinusoidal load 針對(duì)浸泡在液體中的懸臂梁試件和四點(diǎn)彎曲試件,計(jì)算了在受躍階載荷和正弦載荷作用時(shí)的變形、流動(dòng)以及流動(dòng)電場分布。
It is a new truly mesh - less method , because the background cells for integration are not needed . it uses the weighted function of gaussian or of spline as a test function of the weighted residual method 這種方法采用高斯權(quán)函數(shù)或樣條函數(shù)作為加權(quán)函數(shù);同時(shí)這種方法只包含中心在所考慮點(diǎn)處的規(guī)則局部區(qū)域上以及局部邊界上的積分;所得系數(shù)矩陣是一個(gè)帶狀稀疏矩陣。
