To All, I know that equivalent plastic strain that you output using PEEQ command is cumulative, positive, scaler quatity but does it increase everytime the strain goes above yield or when it exceeds the previous max value. Assume you have a cyclic compressive load on an element. The load stays...

What is the best software to do filter. I need create an 8th order low pass butterworth filter. Also from what I remember from by signal processing class (which was a long time ago) that filtering causes a time delay and phase shift. What is the best way of eliminating it or reduce the...

I have sqare tube that is 9 inch wide x 1 inch long x 1 inch thick. It is going to get loaded in compression along 1 inch length. Is it ok to model it as a shell element? Thanks in advance rh142

Which material model would be best suitable if I wanted to model a material which will have to strength in tension but have some strength in compression and after yield in compression let it behave perfectly plastic. Thanks in advance

ANSYS help recomends that if SSTIFF is used for non-linear buckling analysis adaptive decent should be turned off to get a lower bound. What if SSTIFF is turned off? I have found that adaptive descent is helpfull when doing elastic-plastic analysis, turning it off will give an unrealistic low...

I am running a transient dynamic analysis in ansys, at some time point it is failing to converge and the MAX DOF INC bounces back and forth between two point. I am including a sample. It bisects soon and converges but the same bouncing happens again and again. Eventually it reaches the limit and...

Should engineering or tru stress-strain curve be input for material properties. Thanks,

To All, After running a modal analysis in ANSYS, you get participation factors in all DOFs. Can you combine these directional participation factor by SRSS and get a one value. Thanks in advance

Is there an equation to smear the modulus of elasticity of rebar on a solid element. I have a 3D model of a concrete structure and only the concrete is modeled as an isotropic material. The natural frequency is coming out to be too low. I wanted to smear the stiffness of rebar without...
