Objective
This is a short course on the advance options in LSDYNA. This course provides more information on the options in LSDYNA such as elements, material, contact, hourglass, damping, etc. The course will provide more understanding of what options users should use for their particular situation. Examples are used to illustrate the points made in the lectures.
Audience
This course is recommended for engineers who want to understand LSDYNA in more detail and learn advance topics in impact finite element simulation. This course is useful for engineers and researchers who are working in the area of impact, crashworthiness, metal forming, deformation and strength of isotropic and most common materials, as well as those who are working on biomechanics problems.
Notes
The instructor for this course is Dr. Ala (Al) Tabiei. Please contact Al for a more detailed course description (atabiei@aol.com, 513-331-9139). Lectures begin daily at 9:00 a.m. and run until 5:00 p.m.
