Interactive simulation of eigenmodes for instruction of finite element behavior
This paper introduces a new approach to teaching and learning finite element behavior through the interactive simulation of eigenmodes, using a finite element analysis program with functions specialized for this purpose. The eigenvalues and eigenvectors of the stiffness matrix are interpreted in terms of displacement and strain energy modes representing the basic characteristics of an element or an assembly of elements.
