Nonisothermal constitutive model for the small strain behavior of 9Cr-1Mo-V-Nb pressure vessel steel

Article Abstract:

The nonisothermal behavior of a 9Cr-1Mo-V-Nb pressure vessel steel at varying temperature levels is studied with respect to the system strain using a viscoplastic constitutive model. The important parameters involved in the vessel's isotropic and kinematic processes are presented in the form a simple flow equation. Results indicate that the model is capable of predicting the vessel's thermomechanical responses except the relations between the strain rate and the system's strain softening behavior.

Interfacial stresses and void nucleation in discontinuously reinforced composites

Article Abstract:

Research shows that when reinforced composites are experiencing strain, the interfacial normal stress maximum is linearly dependent on the Mises and hydrostatic stresses which in turn influence void nucleation process.
