但是,如果不想基于全局坐标系输出,那你可以自定义一个local system。那么odb中的输出变量就基于local system了。在large-displacement simulation 中,local system 会随节点而旋转。A.2 Shell Elementshell elems 有两种:continuum shell conventional shellconventional shell 在单元形状上是2d的(三角形或者四边形);...
SPRINGA Axial spring between two nodes, whose line of action is the line joining the two nodes. This line of action may rotate in large-displacement analysis. (Abaqus Analysis User's Manual Section 26.1.2) STRI3 3-node triangular facet thin shell (Abaqus Analysis User's Manual Section 23.6...
接下来使用一个热-力耦合步骤（Coupled Temp-Displacement）来模拟温度场和结构响应的相互作用。
ABAQUS第6讲：非线性分析
For a large-displacement analysis the scale factor is 1.0 by default. Set the displacement magnification factor to 1.0 so that you can see the actual displacement, and redraw the displaced shape plot. Hint: You will have to use the Common Plot Options dialog box. 6. Create a contour plot ...

经典矩阵形式:[M]是质量矩阵,是对称且正定的; [C]是阻尼矩阵;[K]是刚度矩阵;(may include large-displacement effects, such as “stress stiffening” (initial stress terms);可能不是正定的或对称的;);μμ是特征值,{ψψ}是特征向量(即振动模式)将abaqus中经典矩阵形式的方程和方程(12)对比,可以看出:...
The analysis may need a large number of increments (more than 20,000,000), and it may be affected by round-off errors. For accuracy, running double precision executable is required. 2022-05-19 回复2 百分之一十七 双精度 2023-02-07 回复1 醉是不省事 百分之一十七 咋改...
