p-Element
This tutorial pleted using ANSYS The purpose of this tutorial is to outline a simple coupled thermal/
Element Death structural analysis. A steel link, with no internal stresses, is pinned between two solid structures at a reference
temperature of 0 C (273 K). One of the solid structures is heated to a temperature of 75 C (348 K). As heat is
transferred from the solid structure into the link, the link will attemp to expand. However, since it is pinned this
cannot occur and as such, stress is created in the link. A steady-state solution of the resulting stress will be found to
Index simplify the analysis.
Loads will not be applied to the link, only a temperature change of 75 degrees Celsius. The link is steel with a
Contributions modulus of elasticity of 200 GPa, a thermal conductivity of W/m*K and a thermal expansion coefficient of 12e-
6 /K.

Preprocessing: Defining the Problem
According to Chapter 2 of the ANSYS Coupled-Field Guide, "A sequentially coupled physics analysis is the
combination of analyses from different engineering disciplines which interact to solve a global engineering problem.
For convenience, ...the solutions and procedures associated with a particular engineering discipline [will be referred to
