怎样在Ansys中实现shell91和solid92单元之间的耦合？

zhjyapu

各位大侠，兄弟我最近做一个有限元的分析，需要用shell91模拟一个三层厚的复合板，用solid92模拟箱型梁，梁的高度与复合板的厚度相同，或者也可以采用shell93来模拟这个箱型梁。但是在两个单元之间怎样实现耦合呢？请大侠们不吝详细指教，之前我是一点都没有做过这种耦合分析。谢谢了！

用mpc技术，论坛有很多相关的帖子

实在不好意思，什么是mpc技术啊？真是不懂啊

MPC184 comprises a general class of multipoint constraint elements that apply kinematic constraints between nodes. The elements are loosely classified here as “constraint elements” (rigid link, rigid beam, and slider) and “joint elements” (x-axis revolute, z-axis revolute, universal, slot, point-in-plane, translational, x-axis cylindrical, z-axis cylindrical, x-axis planar, z-axis planar, weld, orient, spherical, and general). The constraint may be as simple as that of identical displacements between nodes. Constraints can also be more complicated, such as those modeling rigid parts, or those transmitting motion between flexible bodies in a particular way. For example, a structure may consist of rigid parts and moving parts connected together by rotational or sliding connections. The rigid part of the structure may be modeled with the MPC184 link/beam elements, while the moving parts may be connected with any of the MPC184 joint elements.

呵呵 好好看看书吧  
mpc184 是很好的东东
