The coupon undergoes a simulated tensile test, where one end is held via a series of single
point constraints – colored in blue in Figure 1. The other end is
drawn along the positive x-axis via an enforced displacement applied at the center of the
rigid element – colored in green in Figure 1.
The enforced displacement loading is applied via two subcases. The first subcase applies
SPCD displacement of 0.2117, which is in the elastic domain, and then subcase 2 goes up to
SPCD displacement of 17 mm (which includes plastic deformation).

Results
As expected, the coupon is elongated by 17 mm resulting in a maximum strain (von Mises) of
0.1262 – illustrated in Figure 2 and 780 MPa of stress (von Mises). Figure 2. Elastic-plastic Element Strain (von Mises) Contour Plot
