Abstract: Many structural members in service experience fluctuating loads and temperatures. Thermal stresses devlop on a contrained element if the temperature is cycled. Constraint exists in structural ...

Abstract: Two state variables, strength and internal (back) stress, were determined during cyclic deformation by rapid unloading-reloading experiments. The experiments were performed at different temperatures ...

Abstract: Beginning in April 2008 there will be a change in the JEMT masthead. Dr. Hussein M. Zbib's name will appear as Editor, and my name will join those of the former editors. Dr. Zbib, who ...

Abstract: I am very pleased to succeed Prof. David McDowell as the new Editor of Transactions of the ASME, Journal of Engineering Materials and Technology. I would like to thank David for his strong ...

Abstract: Material behavior under thermo-mechanical and isothermal loading cases is studied. The influence of constraint on thermo-mechanical deformation behavior is identified using a two-bar structure. Some ...

Abstract: Mechanisms and models proposed for plane strain fatigue crack closure are evaluated. A mechanism based on out-of-plane plastic strain component, εz p , in plane strain is shown not to be ...

Abstract: A non-unified creep plasticity constitutive model and a unified creep-plasticity model have been considered. In the non-unified model, creep and plastic strains were added separately; in the ...

Abstract: Deformation and damage behavior of a 1070 steel (class U wheel steel) under thermo-mechanical and isothermal loading have been examined. Fatigue lives under thermo-mechanical and isothermal loading ...

Abstract: Thermomechanical fatigue (TMF) and isothermal fatigue (IF) experiments were performed on bare Mar-M246 as well as bare and coated Mar-M247 nickel based superalloys at strain ranges from 0.335 ...
