Hi everybody! I'm analyzing with Patran and Nastran a multi-arch structure where the arches are made of a sandwich material (so I used 3D elements for the core e 2D elements for the upper and lower faces). The problem that I have is related to the boundary condition because as you can see in the...
Hi everybody, I'm working on my thesis and the project is about a martian habitat. So for the moment, I'm trying to analyze a hemispherical structure that is represented in the figure. The problem is that I'm searching for a rapid way to describe the shielding regolith (or soil it depends on how...
Hi guys!
First of all, I'm new to this forum and this is my first thread, so if there are some mistakes in the way that I posted it tell me. Anyway, I'm working on finite element simulation with Patran and Nastran on a particular composite material, actually, we can say it's a sandwich. I'm...
