Using ANSYS, plot the deflection, bending moment, and shear force distribution of the beam. If you have four elements, what is the optimal mesh? Repeat the solution with an eight-element mesh. Comment on the results. Is your solution right? How can you improve the finite element solution?
- If your model is not sufficiently constrained, you'll get a solver pivot error since the algebraic equations generated will not have a unique solution. What are the displacement and rotation constraints that need to be applied in your ANSYS model so that you don't get the solver pivot error?
- What is the total no. of degrees of freedom that ANSYS puts in for the four-element mesh?
- Bending moment: Trend from A to Ba. Do you expect linear, quadratic or cubic variation?b. Does the ANSYS solution within each elementshow element show this trend? Why or why not?
