Hello, I am a PhD student in Mechanical Engineering, and at the moment I am studying the co-rotational formulation from Criesfield's books.
I am looking for applications of the corotational formulation in ABAQUS or MATLAB; my supervisor suggested me it could be done in ABAQUS through a User Defined Element Subroutine, but being a new user to this software I don't really know from where I should start.
I found great help in this previous discussion on iMechanica - http://imechanica.org/node/4880 - and the papers it refers to, where the author describes the necessary steps to follow for a corotational-based FEM in MATLAB, but unfortunately no code is provided.
If anybody could help me, it would be much appreciated.
Thanks in advance to anyone who would reply,
Dario
