What are values of *potential in abaqus?

Potential option is used to define stress ratios for anisotropic yield and creep behavior. The help file only gives the six symbols namely R11,R22,R33,R12,R23,R13. I am using Aluminium. Can...

Can one suggest what might be wrong with the analysis on Abaqus, as the sheet is not showing any plastic deformation even after 4mm depth of cut?

I am simulating Single point incremental forming on Abaqus CAE. Analysis completes successfully but i am not getting any plastic deformation on sheet. I gave an absurd value of 4mm depth of cut...

How can I define circular tool-path in Abaqus-CAE?

I am simulating single point incremental forming and intend to get the profile "truncated-cone" on sheetmetal. How do i define the tool-path for this? For profiles like truncated-pyramid, when...

How to reduce analysis time on Abaqus?

My model is taking 12 hours to complete analysis and i have defined just one step. Each step is of roughly 150 seconds and i have atleast 12 such steps. So, i need general tips, such as increase...

How do I correctly specify a part as rigid body in Abaqus CAE?

There are two parts in model, a sheet and a tool. I defined tool as rigid body using constraint manager. By doing that I get a warning. warning: "Each of the nodes in node set...

How can I define displacement boundary condition and amplitude in Abaqus CAE?

I need to move the tool along negative y-axis for which I have given value of U2:-150 (mm) and in amplitude: tabular I gave as time/amplitude as 0/0 and 1/1. Also, in the second step, displacement...
