I am performing a nonlinear analysis of a titanium tube using in hydraulic application. My stress-strain curve has zero slope in non-linear range. This is the first time I use the program to do nonlinear analysis. Before this, I used NASTRAN to do the job. The result from NASTRAN looks good to me. However, for the result from I-DEAS, I got the maximum von-mises stress more than the yield stress. If I understand correctly, the max von-mises stress at the critical load should be not more than the yield stress. I don't know what I did wrong. Here is the information of my model.
- nonlinear analysis of titanium tube using in hydraulic application.
- Arc length method to find the maximum internal pressure.
- Yield strength = 105 ksi
- Young's modulus = 15000 ksi in elastic range and 0 in inelastic range
- Ultimate strength = 125 ksi
- poisson's ratio = 0.361
Can anyone tell me how to perform nonlinear analysis using I-DEAS?
TIA
