Abstract: The fixed-point iteration algorithm is turned into a quadratically convergent scheme for a system of nonlinear equations. Most of the usual methods for obtaining the roots of a system of ...

Abstract: A viscoplastic constitutive model is described in which deformation behavior is postulated on representative slip systems and the behavior of the entire crystal is determined by summing the slip ...

Abstract: The activation energy for creep at low stresses and elevated temperatures is associated with lattice diffusion, where the rate controlling mechanism for deformation is dislocation climb. At higher ...

Abstract: A viscoplastic theory is developed that reduces to creep theory analytically under steady-state conditions. A fairly simple model is constructed from this theoretical framework by defining material ...

Abstract: The elevated temperature, uniaxial inelastic deformation behavior of a Ni-base alloy, B1900 + Hf, has been investigated by performing isothermal tensile, creep, cyclic, stress relaxation, and ...
