Why is XFEM a revolutionary technique in modeling fracture?
eXtended Finite Element Method or XFEM is a revolutionary technique in the field of fracture mechanics since it lets one model a propagating crack without use of a focused mesh and without any previous knowledge of crack location. XFEM has several advantages over traditional techniques including ease of initial crack definition, improved convergence rates for stationary cracks and simpler mesh refinement studies.
In this eSeminar we focus on basic XFEM concepts, damage modeling within XFEM and creating an XFEM crack growth model within Abaqus. There is also a short demonstration showing crack growth behavior in a three-point bend specimen.

Presenter
Dr. Arun Krishnan – Technical Sales Specialist
Dr. Krishnan has been with Dassault Systemes since November 2012 as Technical Sales Specialist for the following SIMULIA products: Abaqus, Isight, Tosca and fe-safe. He received both his MS and PhD at Vanderbuilt University, where he focused in Fracture & Failure and High Performance Composites.
Dr. Krishnan teaches several Abaqus-based and Tosca-based courses including Intro to Abaqus, Contact, Abaqus/Explicit, Composites, and Fracture-Failure with Abaqus. He is the in-house expert for composites and fracture techniques in finite elements.
