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.
