Abaqus simulation of bonding mechanism in cold gas spraying with particle impact and critical velocity results
Cold Gas Spraying & Shot Peening: A clear, practical guide to simulating high-velocity impacts

Cold gas spraying and shot peening may look different at first glance — one deposits material, the other changes the surface — but both are driven by the same physics: high-velocity impacts that create intense, highly localized plastic deformation. That

large deformation via user material
Large Deformation in ABAQUS via UMAT

1. An Introduction to Non-Linear Continuum Mechanics Finite deformation (also called large deformation or finite strain theory) is a framework in continuum mechanics that describes the behavior of materials undergoing significant volume changes, where strains and rotations are not small.

FEM simulation of martensitic transformation during welding Solid phase transformation welding
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

Illustration of thermal expansion causing material stress
Thermal Expansion: Holding bad boys in their prison

Confession Time: I sometimes totally underestimate thermal expansion it looks so innocent on paper! 🤓 Let’s break it down: We’ve all seen that classic formula strain = ΔT × α, where α (alpha) is the material’s “how much do I

History of FEA COMPUTATION TIME
History of FEA Computation Time

In the past decade, processor performance has increased significantly, leading to a huge jump in computational speed. For example, the first computers, such as the ENIAC, could perform 385 multiplications per second, whereas modern processors can perform more than 11

Creep strain vs stress relaxation
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,

Finite element simulation of stent foreshortening in a coronary artery
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

Comparison of hyperelastic materials and linear elastic models
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

My FEM Software Journey: The Good, The Bad & The “Aha!” Moments

I’ve been quiet for a while, but for good reason—more on that later. Today, I’m sharing the messy, challenging, and surprisingly fulfilling path I took to learn commercial FEM software. If you’re navigating the same struggles in your FEM software

Linking Abaqus and FORTRAN: A Step-by-Step Guide
