First of all, thank you for all your guys to give me the help. Yes, the first input point is (0.00095,26,100) instead of (0,0). (0,0) is the default point in Ansys, which I believe. As Scofie pointed out, I considered the geometric nonlinearity in the linear model, then the results are just...
Thank you, fsi.
The material is 304 S.S. My first point is the point where the material shows deviation from the linear slope (E=27.5ksi). The point is appoximate at strain=0.00095 and stress=26,100 psi. When the strain-stress range is in the linear elastic zone, why did I get the quite...
I am using Ansys 7.0 to do a FEA on a torispherical head subjecting to internal pressure. According to my understanding, I should triger a nonlinear (material) analysis, especially at a thinner head thickness. I started at a thicker head thickness which limit the stress-strain relationship in...
