Abstract: Direct quantitative comparisons are drawn between the predictions of two state-variable constitutive theories, that of Hart and a recently-proposed theory due to Robinson, for a number of simple ...

Abstract: A new approximate theory for wave propagation in a periodically layered elastic body is proposed. In its present state, the theory is valid for either propagation normal to the layering or ...

Abstract: We outline here a method for incorporating the scatter observed in creep rupture times and fatigue cycles-to-failure into a probabilistic model for creep-fatigue failure. We do this within the ...

Abstract: A notable feature of replicated creep and creep-rupture data is the considerable amount of statistical scatter present. The existence of this scatter leads to substantial uncertainties in the ...

Abstract: Numerical results are presented for the dispersion spectrum for harmonic wave propagation in an unbounded, periodically layered elastic body in a state of plane strain. Both real and complex ...

Abstract: The propagation of horizontally polarized shear waves through a periodically layered elastic medium is analyzed. The dispersion equation is obtained by using Floquet’s theory and is shown to ...

Abstract: The problem of harmonic wave propagation in an unbounded, periodically layered elastic body in a state of plane strain is examined. The dispersion spectrum is shown to be governed by the roots ...

Abstract: We outline here a simple approximate method of lifetime prediction for high-temperature, internally pressurized piping components that takes into account the very large scatter present in the ...
