Abstract:This paper introduces a generalized viscoplastic model and describes its application in treating the longitudinal fracture of inhomogeneous beam structures. The model is a combination of an arbitrary number of parallel units. Each unit is obtained by two springs and a dashpot. Besides, a frictional slider is placed parallel with one of the springs in each unit of the model in order to treat the plastic strains. The time-dependent constitutive law of the model obtained by considering strains, stresses and equil… Show more
