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.
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?
Modeling a Stacked Piezoelectric Actuator in a Valve
Piezoelectric valves are energy efficient, durable, and fast. You can model a key component of this device responsible for opening and closing the valve: a stacked piezoelectric actuator.
Simulating the Insertion of a Snap Hook
Snap hooks, a type of fastener that involves the insertion of a hook into a slot, are found in the automotive industry. Simulation can be used to analyze their insertion and removal.
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.
