Y1 - 1986. N2 - The material model consists of a viscoelastic Burgers element and an additional viscoplastic element, which includes Bingham viscosity and a viscoplastic Kelvin element. viscoelastic viscoplastic material that also experience stiffness degradation. A general thermodynamically consistent theory of nonlinear viscoelastic and nonlinear viscoplastic materials was developed by Schapery  and it has been used in simulations by several authors [12,13].

Tests include three stress-strain measurements in the .01-1 /s strain rate range and two high-speed tensile stress-strain curves in the 10-100 /s range covering a total strain rate range of five decades. The purpose of this paper is to investigate the effect of stress classification on cyclic viscoplastic response of a structure (here, a thick spherical vessel which has an application in pressure vessel technology). The response is either reverse plasticity and shakedown or ratcheting behavior of a structure. The viscoplastic behavior of thick spherical vessels subjected to thermo The purpose of this paper is to investigate the effect of stress classification on cyclic viscoplastic response of a structure (here, a thick spherical vessel which has an application in pressure vessel technology). The response is either reverse plasticity and shakedown or ratcheting behavior of a structure.
For this reason, examination of the time-dependent viscoplastic interaction analyses is vital important for monitoring and evaluating of the future and safety of the rockfill dams.

The deformation of essentially all metals is, to a certain extent, time-dependent.
