The time derivative operator does not depend upon the difference between the current time and the past times; however, the fractional time derivative operator does. Thus, it is reasonable to expect that the fractional derivative would be useful in de

The purpose of this paper is to suggest a linear theory of materials with memory, which gives a description for the similarities resulting when the various analytical and experimental methods used to reduce the creep and relaxation data are imposed o

Fractional calculus is used to describe the general behavior of materials with memory. An expression for the fractional derivative or the fractional integral is developed in terms of the Stieltjes convolution and the Riesz distribution. The general f

The theory of deformable porous media is developed based on the principles of Truesdell and Muller. Constitutive equations are developed for the linear theory of a mixture of a viscous fluid and an elastic solid. An example is considered which shows

A method is developed for approximating the three components of the net surface traction vector acting between a tire and its rim. The vector is determined as a function of angular position relative to the footprint, using measured strains in the rim

A method has been developed for measuring diffusion coefficients in liquids to 10 000 atmospheres pressure. Measurements have been made over this pressure range at 0°, 20°, and 40°C for the system CS2–CSS35. The results are interpreted in terms
