... Structures With Homogeneous Kinetic Rate Laws,” ASME J. Appl. Mech., 72, pp. 322–329 ; 2007, “Normality Structures With Thermodynamic Equilibrium Points,” ASME J. Appl. Mech., 74, pp. 965–971 ), are all located in constrained affinity space. Furthermore, the flow potential function monotonically increases...

... rule. One challenge in accurately evaluating the locus of equilibrium conditions is the fact that the relaxation process substantially slow down around these points, and, therefore, a method that does not directly require being at the equilibrium is desirable. Focusing on shear, a thermodynamic theory...

... due to the cycling. By introducing the thermodynamic first principle, a study of the heat equation is developed in order to predict the temperature evolution during a cyclic tensile test. Furthermore, in order to model the damping effect created by the hysteresis phenomenon and the stiffness variation...

...B. Yang; P. K. Liaw; J. Y. Huang; R. C. Kuo; J. G. Huang; D. E. Fielden A high-speed and high-sensitivity thermographic-infrared (IR) imaging system has been used to investigate the temperature evolutions of SA533B1 steel specimens during high-cycle fatigue experiments. Both thermodynamics and heat...

..., thorough discussions are given on the important issues of thermodynamic admissibility requirements for such general descriptions, resulting in a set of explicit mathematical constraints on the associated kernel (relaxation and creep compliance) functions. In addition, a number of explicit, integrated forms...
