Course abstract
This course covers the theoretical and practical aspects of using the Finite Element method in structural analysis. The content includes the basic finite element formulations, the effective implementation of these formulations in computer programs, and recommendations on the actual use of the methods in engineering practice. The course is intended for practicing engineers and scientists who want to solve structural design problems using modem and efficient finite element methods.
