This book covers advanced techniques for the analysis of linear elastic structures by the Finite

Element Method (FEM). It has been constructed from Notes prepared for the course Advanced to

Finite Element Methods or AFEM. This course has been taught at the Department of Aerospace

Engineering Sciences, University of Colorado at Boulder since 1990. It is offered every 2 or 3

years. AFEM is a continuation of Introduction to Finite Element Methods, or IFEM.
