Abstract

As a first stage into the study of the effect of cracks on the dynamic response of beams and portal frames, an elastic analysis is presented. The method combines dynamic photoelasticity with a computer program based on the finite difference formulation of the equations of elasticity. The method is compared to an analytical approach using the Timoshenko beam theory. It is concluded that a hybrid experimental/mathematical model is the most appropriate for practical purposes.
