Hi,
I used RBE2s to connect two bolted structures together and run frequency response analysis (shell-solid). Ofcourse, the regions where there is no RBE2, structures may penetrate each other in modal analysis as well as in frequency response. My collegue suggest that I should use glued contact...
Hi all,
We simplify our FE model (shell and beam elements) for welded constructions to analyze the entire system. That means we model welded parts as uni-block (i.e. continous parts). After this global analysis, we will analyze the welded parts by incorporating the weld as well in detail. But...
Dear All,
Many structures are made of plates that are welded together. How are we going to model these structures in FE. Assume that I am using shell elements. And I have 90degree corner (crosssection is L shape). I used to use same nodes at the corners of the shell elements (coincident)...
Dear All,
I wonder whether pipeline analysis programs such as Ceasar, AutoPipe etc are enough to satisfy the requirements stated by standards like BS7159, ANSI31.3,ANSI31.3 etc. In other words, would anyone need detailed finite element analysis or analytical calculations to meet the criteria...
We will perform FEA analysis of a plate under blast load. In order to verify our analysis, we need theoretical or experimental solution of a plate under shock loading. This load can be distributed load or a point load. Our aim is to compare our FEA results by changing material data (yield stress...
Dear Sirs,
We are going to develope valves actuated by earthquake. Sensing part may send signal to valve electrically or mechanically.
Do you know any helpful articles, books, web sites about this subject. We are open to collobration with other companies in this project.

I am trying to model a structure made from plates and supporting bars. Think about 2 rectangular plates connected to each other by supporting plates and bars that are perpendicular to 2 plates. As far as I know, if I connect plates perpendicular directly on the same node, I end up with very...
