Beam element formulation with large displacement

More Khaled Megahed's questions See All

In Abaqus python API, is these formulation give the same results?

If 'P' is the part name The first form: P.ReferencePoint(point=(0, 0, 0)) R= P.referencePoints[l] P.DatumPointByOffset(point=R, vector=(10,0,0)) P.DatumPointByOffset(point=R,...

Hi Khaled

Code Aster is open source and has large displacement elements. I suggest you take a look there.

Sincerely

You can use theory of elasticity tools to formulate the problem of large displacement flexure of beams under transverse loads.
