Foreshortening During Stent Expansion: Why It Matters in Cardiovascular Simulations

Intro When placing a stent in a coronary artery, we expect it to hold its shape and position—but did you know that stent length can shorten by up to 10% during expansion? This change, known as foreshortening, is one of

Hyperplastic vs Linear Elastic Materials: Key Differences & Applications

Intro When designing materials for engineering applications, understanding their stress-strain behavior is critical. Two fundamental categories dominate this space: linear elastic and hyperelastic materials. Here’s what you need to know and why it matters. Linear Elastic Materials: Simplicity at Small

Acoustic Metamaterials and Metasurfaces: Shaping the Future of Sound Control

Intro Acoustic metamaterials and acoustic meta surfaces are changing how we control sound waves. These specially designed structures go beyond the limits of traditional soundproofing. They offer new ways to control sound, such as reducing noise over a wide frequency

OpenSees software simulation of nonlinear seismic response in a reinforced concrete frame
