HI FRIENDS.

I AM WORKING ON NON LINEAR BUCKLING ANALYSIS PF COMPOSITE PLATE USING ANSYS SOFTWARE.I HAVE GIVEN GEOMETRIC IMPERFECTION USING FIRST BUCKLING MODE SHAPE.DID A NON LINEAR DISPLACEMENT CONTROLLED ANALYSIS.PROGRAM IS TERMINATING WHEN PROGRAM IS RUNNING.CAN ANYBODY HELP PLS. I WANT LOAD DISPLACEMENT CURVE .I AM WORKING ON COMPOSITE FLAT PLATE.

Curie Temperature

Most technologically relevant ferroelectrics typically lose piezoelectricity above the Curie temperature. This limits their use to relatively low temperatures. In this Letter, exploiting a combination of flexoelectricity and simple functional grading, we propose a strategy for high-temperature electromechanical coupling in a standard thin film configuration.

Crack Propagation by XFEM

Submitted by anthony_wong on

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.

ABAQUS

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
