Tutorial: Nonlinear static stress analysis

This tutorial shows you how to perform a Nonlinear Static Stress study on a highly loaded tapered beam. The model and simulation study have the following characteristics:

• The high-strength / low alloy steel material is available from the Fusion Nonlinear Materials library. This material has a predefined plastic stress-strain curve.
• The beam is loaded with a 300 kN downward force acting on the central portion of the top flange. The top face has been split to confine the load to the desired portion of the flange.
• The beam is constrained at the short bottom faces located at each end of the beam. One support is fully fixed, and one is held in the vertical and transverse directions (leaving it free to float axially as the beam deforms).

In this tutorial, you

• Create a Nonlinear Static Stress study to see how a load affects a beam made of a material with nonlinear behavior

• Select a material and confirm that it shows nonlinear behavior

• Apply constraints and loads to simulate the experience of the beam under load

• Run a nonlinear static stress analysis to see if the beam can support the load, given the material selection.
