ADVANCED CONTACT & FASTENERS

SEMINAR OUTLINE

 

From contact stiffness and friction to surface-to-surface, node-to-node and bolt pretension elements, this two-day course is designed to analyze contact models that cannot be readily solved using default settings. Hands-on workshops are used throughout the course.
