Tips for FEM Analysis of Solid Phase Transformation During Welding
Welding is one of the most critical processes in mechanical and structural engineering. Beyond simply joining metals, it introduces complex thermal cycles, stress fields, and microstructural transformations that can significantly affect the performance of the welded joint. For high-temperature steels like P91, understanding these transformations is essential for predicting residual stresses, hardness distribution, and service […]
Creep Strain vs Stress Relaxation, A practical guide for CAE users
Description Learn what creep is, how temperature and stress control creep life, and which creep models CAE tools (ANSYS, COMSOL, Abaqus and others) use. Simple equations, practical CAE workflows, ASME / code context, and industrial project examples (boilers, pressure vessels, turbines, heat exchangers). What is creep? Creep is permanent deformation that accumulates over time when […]
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 the key challenges in ensuring accurate and safe stent deployment. At EngineeringDownloads.com, we’ve been running […]
Hyper Elastic 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 Strains Linear elastic materials follow Hooke’s Law, where stress is directly proportional to strain. Think of a spring: pull it […]
