Hi,
I've worked a lot with topology optimization in my research and I know through contacts in industry that the method is used (but not widely) to solve practical problems. It's a beautiful method for doing really basic design but keep a few things in mind.
First, you should start out with a...
Hi,
I just want to make a comment regarding the original point b).
As zuardy points out, numerical integration has to do with hour-glass modes, which are in fact zero energy modes resulting from an insufficient order of numerical integration (in the Gauss quadrature).
Many shell and plate...
Hi everyone,
I was just wondering if some of you have any experience with obtaining bending-moment diagrams in Ansys. I have figured out a way but it is tedious to say the least. In brief I currently have to define an Element Table with SMISC,6 and SMISC,12 entries and plot the Element Table...
Hi,
In my experience the use of shell elements require a good deal of insight since a number of things might go wrong. On the other hand it can often be difficult to obtain usefull results when modelling shell/plate structures with solid elements (e.g. 8- or 10 node). Simply because a large...
