Introduction to LS-DYNA


Learn how to run LS-DYNA to solve engineering problems. Detailed descriptions are given of the data required to run LS-DYNA analysis. Examples are used to illustrate the points made in the lectures.


This course is recommended for engineers who want to use LS-DYNA to perform nonlinear static and dynamic impact simulations. Engineers working in the aerospace, automotive, and civil, manufacturing, packaging industries and government organizations will benefit from this course. This course is useful for engineers and researchers who are working in the area of deformation and strength of isotropic, composite, and most common materials as well as those who are working on biomechanics problems.


Intro to LS-DYNA Instructors: Depending on dates will be either Dr. Ala (Al) Tabiei Or Professor John Reid. Lectures begin daily at 9:00 a.m. and run until 5:00 p.m., except for the last day when the course concludes at 12:00 p.m. The classroom machines are PCs running Linux (CA) or Windows (MI).
