Pre-Analysis Calculations

It is important before using a tool such as redAnTS to obtain some information about the solution; otherwise, you risk obtaining an incorrect solution with no basis for comparision. In this example, we know that since the block is in uniaxial tension, it should have a homogeneous state of stress and strain i.e. the stress and strain at every point in the block is identical. Yup, couldn't get simpler than that! The principal stress σ₁₁= 75 MPa. Later, we will compare this value against the output of redAnTS to make sure we modeled the problem correctly. We are now ready to attack the problem using redAnTS.
