抄録

The authors discuss the validity of the results obtained experimental and numerical analyses for the viscoelastic boundary value problem under a typical type of non-proportional loading condition. A rectangular viscoelastic strip plate made of epoxy resin is loaded by a cylindrical hard roller moving along the upper straight edge. A convenient computer image processing aided photoviscoelastic method is applied to investigate the time dependent principal stress/strain difference and principal directions of stress/strain around a contact region. On the other hand, a finite element method-FEM -is attempted to analyze the viscoelastic stress and strain under several conditions. The time variations of photoviscoelastic fringe pattern are compared with the contour bands of principal stress/strain differences qualitatively, and the time variations of principal stress/strain differences and directions of principal stress/strain under non-proportional condition, are evaluated at which the material shows remarkable viscoelastic and rubber-like behavior.
