Accessing External Material Models for Structural Mechanics
In COMSOL Multiphysics®, you can access not only material models derived from external libraries but also material functions programmed by yourself. We demonstrate with concrete damage model.
Using Simulation to Analyze Arterial Wall Mechanics
Studying arteries from a mechanical standpoint requires a reliable model that can fully describe the anisotropic nonlinear response of this biological soft tissue.
Finding a Structure’s Best Design with Topology Optimization
Think about the first architects who designed a bridge above water. The design process likely included several trials and subsequent failures before they could safely allow people to cross the river. COMSOL Multiphysics and the Optimization Module would have helped make this process much simpler, if they had computers at the time, of course. Before we start to discuss building and optimizing bridges, let’s first identify the best design for a simple beam with the help of topology optimization.
What Is Geometric Nonlinearity?
If you perform structural mechanics analyses, then you have most likely encountered the concept of geometric nonlinearity. But what exactly does geometric nonlinearity mean?
The Physics of Tennis Racket Sweet Spots
Whether you’re a tennis pro or new to the courts, you might enjoy this blog post examining the physics behind the “sweet spots” of a tennis racket.
New Simple Mechanical Cloaking Technique
Researchers from the Karlsruhe Institute of Technology developed a simple mathematical technique for designing mechanical cloaks using numerical modeling. Get details here.
The MTC Builds a Simulation App to Optimize 3D Printing
