hello Dear friends

I am working on geometrically nonlinear behavior of 2D beam.

I used field consistent approach using total lagrangian. because of field consistency, satisfication tangent stiffness matrix is dependent to tangant of node angles. this means that when beam is subjected to pure bending when angle of rotation approches to 90 degree, tangent stiffness matrice become singular. can any one give solution to this problem. how about corotational formulation.

thanks a lot.

best regards.

Hi,

Can any one know the way to give and impact force in  ANSYS workbench static structural ?

Thanks 

Hi,

Hai everyone.

Good day, i'm a new to XFEM who currently doing research in electronic field. I'm thinking about since the crack can be propagated without a crack tip by strain loading, how about the crack propagation by using thermal loading? I didn't see any example of this kind of problem, so can anyone tell me is that possible to do such simulation? Your suggestion is important for me and will be highly appreciated.  

Thanks in advance.

Hi everyone,

I am trying to get the history output of strain and stress tensor components at a node. However after analysis is finished no such data are saved in the result section. I think Abaqus only gives the stress and strain for elements and not at nodes. Any help would be highly appreciated. Please consider that I am a new abaqus use.

Thank you in advance
