Abstract: Linear equations of motion are derived to describe the behavior of small disturbances in a porous solid containing both liquid and gas. Appropriate boundary conditions are derived to guarantee ...

Abstract: The basic problem addressed here is that of obtaining the unknown retardation time spectrum from experimental creep response curves. The spectrum may be a set of discrete times or it may be ...

Abstract: The method of constrained regularization is used to invert for retardation spectra and attenuation from the creep data of a commercial-grade lucite material. Four different criteria for choosing ...
