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
