Abstract This article presents an overview of time dependence in the mechanical properties of materials, and of the methods to describe it.
Abstract Measurements are described and analyzed for the determination of thedynamic bulk compliance for Poly(vinyl acetate) [PVAc] as a function offrequency and temperature at atmospheric pressure to generate a mastercompliance curve over a total frequency range of about 12 decades.Measurements...
Abstract This study discusses several types of contact, involving compression andsliding, between a time-dependent material and a rigid body. Itdemonstrates a useful application of a new hybrid method forphotoviscoelastic stress analysis under non-proportional loadingconditions, in which the...
Abstract This paper deals with time-dependent small-scaleintergranular fracture in metals at high temperatures. First, diffusional cavitation during fatigue isdiscussed in terms of its mechanism. Creep cavitiesand cavity-type cracks nucleate and grow inside thematerial under combined very slow...
Abstract The multidata method was originally proposed to fit a Prony exponentialseries function to experimental viscoelastic modulus and compliance data;this was accomplished by the application of a linear least squares solver.This paper considers a similar approach, but extended in two key...
Abstract This paper analyzes molecular dynamicssimulation results on the small-molecule glass formerortho-terphenyl (OTP). The data can be describedwell using the coupling model of relaxation. Thedynamic susceptibility calculated from thedensity-density time correlation function is shown...
Abstract The damage characteristics near the crack tip and crack growth behaviorin a centrally cracked sheet specimen of a solid propellant wereinvestigated. The specimen was subjected to a constant crosshead speed of0.508 mm/min at room temperature. The effects of local damage andfracture...
