A Strain Range Dependent Cyclic Plasticity Model
Hysteresis loop curves are highly important for numerical simulations of materials deformation under cyclic loadings. The models mainly take account of only the tensile half of the stabilized cycle in hysteresis loop for identification of the constants which don’t vary with accumulation of plastic strain and strain range of the hysteresis loop. This approach may be quite erroneous particularly ...
متن کاملNonlinear Numerical Integration Scheme in Strain Space Plasticity
Strains are applied to the integration procedure in nonlinear increments todecrease the errors arising from the linearization of plastic equations. Two deformationvectors are used to achieve this. The first vector is based on the deformations obtained bythe first iteration of the equilibrium step, and the second is acquired from the sum of thesucceeding iterations. By applying these vectors and...
متن کاملPath Dependency and Path Creation in a Strategic Perspective
Path dependency and, recently, path creation are frequently used concepts in the social sciences. However, they were born as individual issues and in most cases they are still discussed separately. First, the path dependency concept has spread. In the general sense, path dependency refers to the idea that events occurring at an earlier point in time will affect events occurring at a later point...
متن کاملOvercoming path dependency: path generation in open systems
Studies on societal path dependencies tend to focus on mechanisms that anchor and stabilize national trajectories while paying less attention to transnational interactions and multilevel governance. This paper explores processes of path transformation in societies that are presumed to have the characteristics of open systems. Two pairs of case studies are presented and compared. The first illus...
متن کاملToward Dependency Path based Entailment
We present our submission to the RTE2 challenge which takes steps in the direction of dynamically entailing hypotheses via their dependency paths. We evaluate semantic similarity between sentences utilizing corpus co-occurrence estimates of various dependency path features and show a 2.7% improvement on the RTE1 dataset.
