Structures Engineering Courses


Buckling analysis calculates the buckling load factor and associated mode shapes. The buckling load factor multiplied by the applied load gives the magnitude of the compressive load that can cause buckling. In this SimCafe course, you will learn to analyze buckling on a simple column by following the end-to-end workflow in Ansys Structural. 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 immersive step-by-step walk-through videos.

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.

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.

Four-point bending strength is performed to analyze the flexural strength of a material. In this SimCafe course, you 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. 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 immersive step-by-step walkthrough videos.

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.

A femur is the upper bone of the leg. In biomedical engineering, the mechanical properties of the femur can be studied through conducting tests on rat femur.  The valuable data from tests can then be applied in simulation to predict behaviors of other femurs.  In this SimCafe Course, we will show you step by step how to conduct a bending simulation on a rat femur and evaluate the results.

Coronary Artery Disease kills nearly 1 in 4 Americans every year. Implantable stent treatments for arterial disease are constantly evolving with implantable stent innovations leading the way. Over 600,000 cardiovascular stents are implanted every year just in the United States alone. Stents may look relatively simple but are highly engineered lifesaving medical devices. It involves advanced material modeling, complex interaction with the arteries, and extremely high demand for accuracy. Apart from conducting experiments on stents, FEA is a tool that engineers and researchers use extensively to study and design stents. It has the ability to identify some mechanical characteristics of coronary artery stents that may not be easily obtained using traditional mechanical testing. In this SimCafe course, we will go step by step to set up and run a Balloon-Expandable stent simulation.   

The purpose of this SimCafe course is to showcase, in a relatively simple situation, where simple beam theory is no longer as valid as it is in the limit of a long and slender beam geometry.  In some commercial codes, simple one-dimensional cubic beam elements for bending deflection, do not capture shear deflection when the beam is no longer slender. Alternatively in Ansys, if shear deflection is accounted for in the 1D element formulation, results for the beam’s tip deflection will not agree with tip deflections predicted by simple Euler-Bernoulli beam theory. This course is meant to highlight where it is relatively straightforward to apply 3D FEA and resolve a correct solution.
