Papers by Keyword: Generalized Model

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 equilibrium of the model components is used in deriving solution of the strain energy release rate for the longitudinal crack in the viscoplastic beam.

Abstract: In the literature only a handful of studies have been performed on the distributed deadlock problem in the generalized request model. Most of those algorithms use either the diffusing computation technique or have the initiator collect all the dependency information among processes. This paper proposes an algorithm which incorporates these two methods with the following properties: first, it removes the reduction phase of the diffusing computation; second, it encodes the dependency information to reduce message length, rather than transmitting it naively as is. The main advantage of the proposed algorithm is that deadlock detection time is reduced to almost half of that of the existing algorithms.
