Abstract

Abstract

Based on convolution-type co nstitutive equations for linear visco elastic materials with damage and the hypotheses of Timoshenko beams,the equations governing quasi-static and dynamical behavior of Timoshenko beams with damage were first derived.The quasi-static behavior of the viscoelastic Timo shenko beam under step loading was analyzed and the analytical solution was obtained in the Laplace transformation domain.The deflection and damage curves at different time were obtained by using the numerical inverse transform and the influences of material parameters on the quasi-static behavior of the beam were investigated in detail.
