Hi
I am trying to model a cantilever beam (mem’s scale).
The beam is constructed from two materials; Aluminium layer (colour green) on top of a Silicon dioxide base layer, see attached database model. The element type is solid 45, (unsure if this is correct element type for this type of analysis)
I want to induce a compressive pre-stress in the silicon dioxide layer of around 80Mpa and a smaller tensile stress of 10 Mpa in the Aluminium layer. I am hoping this will cause the beam to curl/deflect in one direction. I do not wish to apply any other type of loading on the beam.
I am assuming a modal analysis (unsure if this is correct assumption)
Question:
How do I induce a pre-stress in a material layer and solve it, so it causes the beam to curl/deflect. I have never done this before. Can you recommend an example or solution?
Regards
