Temperature Loading of a Tapered Cylinder

Temperature Loading of a Tapered Cylinder

This validation test case models temperature loading of a tapered hollow thick cylinder with a spherical bottom flange section. The solid object is assumed to be clamped vertically, but allowed to expand horizontally due to a linear temperature gradient. The stress in the z-direction at the bottom inner point is …

Thermo-Mechanical Bending of a Beam

Thermo-Mechanical Bending of a Beam

Coupled thermo-mechanical multiphysics simulation of bending of a cantilever beam. The left side of the beam is fixed to a solid wall while the top side is subjected to an elevated external temperature through natural convection. The lower and left side are continuously held at the initial zero temperature. A …

Multiple Scale Modeling for Predictive Material Deformation Analysis

Multiple Scale Modeling for Predictive Material Deformation Analysis

A multi-scale modeling and simulation study using FEATool Multiphysics to investigate stretching and deformation of a ligament under uniaxial tension is presented in the following. The study demonstrates how the FEATool simulation software can be used by students and non-experts to perform simulations and quickly get …

Piezo Electric Bending of a Beam

Piezo Electric Bending of a Beam

Multiphysics simulation of piezoelectric bending of a laminated beam as for example can be found in actuators for MEMS (micro electro mechanical systems) devices. The model features coupled plane-stress and electrostatics physics modes with equations modified to account for the anisotropic piezo-electric coupling. The …

Heat Induced Stress in a Brake Disc

Heat Induced Stress in a Brake Disc

This multiphysics model examines temperature and heat induced stresses for one braking cycle in a brake disc assembly, and involves coupling of the stress-strain and heat transfer physics modes. The braking process consists of applying a brake pad to the front part of the disc which induces heat through friction, and …

Stretching of a Thin Plate with a Hole

Stretching of a Thin Plate with a Hole

This example is a well known benchmark test case from structural mechanics, a thin plate with a circular hole in the center is subjected to a load and stretched along the horizontal axis. The plate is thin enough to satisfy the two dimensional plane stress approximation, and since both the problem and solution will be …

Cantilever Beam

Cantilever Beam

A test case for a one dimensional model of a cantilever beam which is fixed to a wall at the left end. Using Euler-Bernoulli beam theory three test cases are studied for which reference solutions are available, a point load at the left end, a uniform distributed load, and the natural vibration modes and frequencies …

Deflection of a Bracket

Deflection of a Bracket

In this example a three dimensional model of a solid bracket with a cylindrical hole is subjected to an external load. The vertical side of the bracket is fixed to a wall (thus zero displacement boundary conditions are applied there), while the outer end of the bracket is loaded with a force of 104 Pa in the negative …

Deformation of a Spanner

Tutorial example of calculating deformation and deflection in a spanner where the geometry is given in and imported from a STL CAD file. This model is available as an automated tutorial by selecting Model Examples and Tutorials… > Structural Mechanics > Deformation of a Spanner from the File menu, and also …

Stress Analysis of a Thick Plate

Stress Analysis of a Thick Plate

This is a benchmark and validation model for linear elasticity where an elliptical thick plate with a hole is subjected to a uniform pressure load of 106 MPa [1]. The outer surface is assumed to be constrained from expansion, in addition to the center line which is fixed in the z-direction. Symmetry is also utilized so …
