*** WARNING *** CP = 2.609 TIME= 09:31:04 For material 1 at temperature 23, the initial slope of the stress-strain curve based on the TB,MELAS table (9500) is less than EX(11000).

I am at work and I am getting this error, any Idea? "joint elements with lag mult option do not satisfy joint constraint conditions" Its still running, will see if it converges Thanks

I am modelling a plastic part in ANSYS 12.2 I applied mesh,connections, forces and suports. I solved and got solution I applied a froce of 1200N Max stress was at 206 MPa UTS of material is at 135 MPa I need to find the force (which should be less then 1200N) at which the part will fail...

I just bought a PDF copy of : This book is awesome, starts from basic and goes into advanced non linear analysis. Must have for someone in FEA field.

I am designing brake pedal. Its made of plastic, I am using CATIA/ANSYS for FEA analysis. Part is within stress limits and sress counters are under yield stress, but during lab test, it fails. I think that I am not modeling plastic correctly in FEA, I am using non linear model. Any Ideas?
