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.
