This tutorial will cover various aspects of element deletion in Abaqus/Explicit, including: *1. Introduction to Element Deletion* *Why Use Element Deletion?* *Material Failure:* Simulating material fracture, cracking, and tearing when a material reaches its ultimate strength or a specific failure criterion. *Erosion and Wear:* Modeling the gradual removal of material due to wear, abrasion, or corrosion. *Damage Modeling:* Implementing advanced damage models that predict crack initiation and propagation leading to element removal. *Simplification:* Removing elements that become detached or are no longer contributing significantly to the structural response, thus improving computational efficiency. *How Element Deletion Works in Abaqus/Explicit:* When an element meets a pre-defined deletion criterion, it is removed from the analysis. This is not the same as setting material properties to zero. The element is physically removed from the mesh, eliminating its stiffness and mass contribution. The removal is usually abrupt within a time increment. Abaqus/Explicit provides parameters to control the smoothness of this deletion process. Careful consideration is required to avoid numerical instability and ensure solution accuracy, especially when deleting elements rapidly or under high stress conditions. *2. Common Element Deletion Techniques in Abaqus/Explicit* Abaqus/Explicit offers several ways to trigger element deletion. The most common are: **Damage Evolution Models (e.g., Johnson-Cook Damage, Ductile Damage)**: These built-in damage models define how damage accumulates within an ... #numpy #numpy #numpy
