It is assumed that you are familiar with the introductory redAnTS tutorial.

Problem Specification

Consider the beam in the figure below. There are two point forces acting on the beam in the negative y direction as shown. Note the dimensions of the beam. The Young's modulus of the material is 73 GPa and the Poisson ratio is 0.3. We'll assume that plane stress conditions apply.

...

We'll put redAnTS to work on solving this problem using FEA. We'll plot displacements and stresses for the beam and make comparisons with theory.

Solution Steps

We can use the same steps as in the introductory tutorial to obtain the FEA solution:
