Variational Methods of Convolution Integral and of Large Spring Constants - A Numerical Comparison
Abstract
Finite element solution formulations have been carried out for a simple initial value problem based on two different variational statements; that of convolutional integral developed by Gurtin and that of large spring constants adapted by this writer for initial value problems. Numerical results indicate that both generate convergent solution to the given initial value problem of a spring-mass system subjected to a harmonic forcing function.
