Cyclic Behavior of Simple Models in Hypoplasticity and Plasticity with Nonlinear Kinematic Hardening
The paper gives insights into modeling and well-posedness analysis driven by cyclic behavior of particular rate-independent constitutive equations based on the framework hypoplasticity elastoplastic concept with nonlinear kinematic hardening. Compared to classical elastoplasticity, in there is no need decompose deformation elastic plastic parts. two different types approaches show some similari...
Using cold working fastener holes is a simple life enhancement procedure that strengthens metallic components by retarding crack growth around a hole. In the present paper, the residual stress field that is induced by the hole expansion process is obtained based on different material models namely elastic perfect plastic, isotropic hardening and kinematic hardening using three-dimensional finit...
An elastic-viscoplastic constitutive material model is developed for the representation of creep response a 10%Cr steel under cyclic loading conditions. It has been shown that able to describe primary regeneration (PCR), i.e. incidence period high strain rate following stress reversal. The variant well-known Chaboche viscoplastic model, and employs bi-term power-law equation represent stress-re...
In this paper, accumulation of plastic deformation of AISI 1045 steel plates with circular cutouts under cyclic axial loading is studied. Loading was applied under force-control conditions. Experimental tests were performed using a Zwick/Roell servo hydraulic machine. Under force-control loading with nonzero mean force, plastic strain was accumulated in continuous cycles called ratcheting. Nume...
