Beyond FEA: An Introduction to Evolving Numerical Methods for Challenging Engineering Problems

Beyond FEA: An Introduction to Evolving Numerical Methods for Challenging Engineering Problems

Finite Element Analysis is a well-established technology with a huge range of applications, but general purpose methods can struggle to solve some classes of problem including crack propagation and large deformation processes. 

Research into more efficient solutions for such problems has developed a range of numerical approaches, and some of the most effective methods have recently been introduced to commercially-available packages.

Whilst these methods have produced impressive results on demonstration problems, their use has yet to become widespread due to lack of familiarity, understanding and confidence within the engineering community. 

Seminar Objectives

The seminar provided an introduction to some of the new methods that are reaching the market, with a strong focus on the pros and cons for practical engineering applications
