The Motions and Mechanics of a Truck-Mounted Crane
The Truck Mounted Crane tutorial model analyzes the forces on the cylinders and hinges of a crane during an operating cycle, combining multibody dynamics and structural analyses.

Obtaining Material Data for Structural Mechanics from Measurements
Linear elastic, hyperelastic, nonlinear elastic, plasticity, creep, concrete: COMSOL Multiphysics® contains a number of built-in material models for structural analyses. Get an intro >>

Evaluating the Instability of a Space Arc Frame
Picture the Louvre Pyramid in France: This is a real-world example of a space arc frame. Simulation can be used to evaluate instability in this type of structure.

Simulating Vibration and Noise in a Washing Machine
When designing a washing machine, you must account for a nonuniform distribution of clothing during operation. Simulation can be used to analyze vibration and noise in this household device.

Introducing Nonlinear Elastic Materials
Examples of nonlinear elastic material models: Ramberg-Osgood, Duncan-Chang, Hardin-Drnevich, Power law, and more. We discuss how to apply nonlinear elastic materials in your analyses.

Biomechanical Model Evaluates Human Response to Vibrations
Take a look at a biomechanical model of the human body in a sitting posture, which can be used to analyze how vibrations (like those from a moving vehicle) affect different parts of the body.

New Piezoelectric Modeling Interface in COMSOL 5.0
As of version 5.0 of COMSOL Multiphysics®, there is a new interface for simulating piezoelectric devices; it has predefined features that make it easy to set up and run a piezoelectric model.

How to Obtain Fatigue Model Parameters
2 challenges when modeling fatigue: 1.) selecting a suitable fatigue model for your application and 2.) obtaining the material data for the selected model.
