KIT Workshop on

Introduction to Non-Linear Finite Element Method

January 15 - 19, 2020

Objectives

Non-linear Finite Element Method has become a very important numerical analysis tool in the field of solid mechanics. With the increasing complexity of problems being handled using FEM in both academics and industry, a basic knowledge of the subject is thus extremely crucial for future scientists and engineers. Hence, this workshop would be very relevant to TEQIP institutions.

The course would cover the basics of linear and non-linear FEM. A major portion of the theory would be explained using one-dimensional examples. Subsequently, multi-dimensional models and development of important segments of non-linear FEM code would be discussed. Few non-linear FEM simulations would be demonstrated as well. Handouts would also be provided to introduce the audience to some more advanced but relevant topics.

Any engineering department dealing with solid mechanics and non-linearity such as Aerospace, Mechanical, Civil, Material Science, Geo-science,etc.
