Homework, Quizzes, Simulation Examples — Thermal Strain — Lesson 5

Simulation Examples

Several simulation examples are provided here. Each of them comes with a description file, video instruction, and Ansys simulation file. All of the simulations are conducted by Ansys simulation experts. Download the student version of the Ansys Software here.

(1) Shape Memory Alloy (SMA) with Thermal Effect

A shape memory alloy (SMA) can undergo large deformations without showing residual strains (pseudo-elasticity) and can recover from large deformations via temperature change (shape memory effect). The pseudo-elasticity and shape memory effect are especially useful for aeronautical, biomedical and structural engineering applications. This simulation concerns applying shape memory as a spinal spacer.  Download the zip file and extract the contents. Go through the Readme file. Follow along with the provided How To Video file.

Homework

(1) Buckling of a Rail Due to Thermal Load

This model analyzes the thermal-strain-induced buckling of a rail. Replicate the simulation and answer the following questions:

(a) Assume an axial load is applied to the rail. Conduct simulation and find out the equivalent load needed to make the rail buckle.

(b) Assume the rail is made of aluminum with twice the thermal expansion coefficient. Conduct an eigenvalue analysis and evaluate the result.

(2) Pipe with Thermal Loads

Pipes may transport hot fluids or gases, causing them to expand at higher temperatures. Engineers need to account for this thermal expansion and the consequent stresses that may occur when designing a transport system of pipes. In this example, we will calculate the amount of deformation a pipe undergoes when allowed to expand freely. We will pay close attention to the boundary conditions applied, to ensure that the pipe is not over-constrained and is, in fact, free to expand due to an increase in temperature.
