Theory Regarding Geometrically Nonlinear 2D Elements
« on: November 28, 2023, 01:21:43 PM »
Hello to all,

I am trying to understand the code in FEAP for modelling a static, geometrically nonlinear, 2D element.
I am currently going through sld2d.f and slowly going through all other internal subroutines it calls, however, I wanted to know if there are any available reference(s) with details on the theory behind the FEM formulation used for creating these files.

Thanks in advance!

Have a look at the FEAP Theory Manual http://feap.berkeley.edu/wiki/index.php?title=Manuals.
Also if you are interest in nonlinear (finite deformation) elements you should be looking, for example, at fld2d1.f.

Element routines starting with “sld” are small deformation and those with “fld” are finite deformation
