Again, it must be stressed that the mesh, geometry, boundary conditions and solver steps have been skipped in this exercise. You are instead given the solutions to the aforementioned problem simulated by ANSYS workbench. You are encouraged to explore these results and understand the different underlying assumptions of the analytical 1D Boundary Value Problem compared to the ANSYS 2D Boundary Value Problem. As you will see, the analytical approach can successfully account for the stresses in the middle of the bar, but fails to accurately model stresses at the point load and end effects.
Displacement:
- Was displacement uniform through the bar?
- Is displacement uniform in the y direction? Is this what you expected?
Sigma_x:
- Is σ_x = P/A through the bar?
Sigma_y:
- Is σ_y = 0 through the bar?
Tau_xy:
