Multiphysics Modeling of Heat Induced Stress in a Brake Disk
Multiphysics Modeling of Heat Induced Stress in a Brake Disk
This tutorial illustrates how to couple a heat transfer model with linear elasticity by manually defining the multiphysics equations with the FEATool PDE syntax. The custom model examines how temperature rise in a brake disk under braking results in heat induced displacements with resulting increased stresses and …
Axisymmetric Stress-Strain Script Modeling
Axisymmetric Stress-Strain Script Modeling
Continuing on the previous post on axisymmetric modeling in FEATool, we will here take a look at how to model axisymmetric stress-strain from structural mechanics by entering and parsing the governing equations directly into FEATool using MATLAB m-file scripting. The problem we will be looking at is a hollow sphere …
Axisymmetric Modeling Using the Custom Equation Syntax
Axisymmetric Modeling Using the Custom Equation Syntax
FEATool has been designed to be able to perform MATLAB multiphysics simulations in all spatial dimensions (1D, 2D, and 3D). However, running full 3D simulations often requires a significant amount of computational resources, that is memory and simulation time. It is therefore desirable to find simplifications to reduce …
