hi

I would like to know how to write a stiffness matrix for a bar under torsional load. I would like to write a code in C++ to do this. I would like to know of any material regarding this.

Thanks in advance

Hi all,

I am currently working on micro-sphere model like the one used by Miehe, Ihlemann and Pawleski. I wonder if someone know a FEM code who use this type of model.

Thanks a lot

i want to create a crack in a cantilever beam, but i m new in this field. please tell me how to model a crack in beam when beam is meshed using 1) beam elements 2) solid elements?

please refer any good tutorials in this field.

Hi everybody

Im working on a project about Finite element modeling of Contact. Im not allowed to use contact solving feature of ANSYS and i should use its Macro Programming. in this case i should read stiffness matrix from ansys, add some row and column to it and input it back to ansys and solve it.

I have two problem with this, first i dont know how to input modiffied stiffness matrix back to ANSYS..
