Four-point bending strength is performed to analyze the flexural strength of a material. This test is useful for materials that tend to crack (brittle failure) under the bending load (like composites, concrete beams, and car axles). A common example of such a material is the electronic PCB. The four-point bending test is conducted on these PCBs to determine their material strength.
This SimCafe course was developed by Rajesh Bhaskaran, Swanson Director of Engineering Simulation at Cornell University in partnership with Ansys; it was last modified by Sebastien Lachance-Barrett. It serves as an e-learning resource to integrate industry-standard simulation tools into courses and provides a resource for supplementary learning outside the classroom. In this tutorial, we will learn to conduct this test, virtually, on a simple T-beam made of structural steel, to understand the boundary condition setup by following the end-to-end workflow in Ansys Structural.

Stepped shafts are widely used in drive trains. Mostly supported by bearings at the end, the shaft experiences bending loads, axial thrust, and torsional loads. The shaft must have greater strength to withstand these loads. In this Sim Café course, you will learn to estimate the axial stress concentration on a stepped shaft under axial tension using Ansys Structural.
Pressure vessels are used in transportation for storage of gases and liquids. Many gases are stored at very high pressure in the liquid form. The pressure vessels are designed mainly to have high strength in both the circumferential (hoop strength) and axial directions. In this SimCafe Course, we will learn to estimate the hoop, axial, and radial stresses in pressure vessels using Ansys Structural.
The design of the telescope truss should be able to sustain dynamic loads and must be flexible enough to provide support for different motions. In this SimCafe course, you will learn end-to-end workflow for importing a realistic geometry and understand the importance of FEA simulations when designing the telescope truss. You will create the computational mesh and set up the boundary conditions needed for the simulation. The fundamental concepts and the steps needed to successfully model this structural problem are explained using step-by-step instructions.
