The role of the presence of a non-deformable second phase in a soft matrix on the plasticity induced crack closure behavior of a growing fatigue crack is analyzed as a boundary value problem using elastic—plastic finite element techniques. Three ca

For many years, researchers have used internal friction to characterize structural inhomogeneities or flaws in a material by using the frequency or temperature dependence of the acoustic loss mechanisms connected with these inhomogeneities. The field

The characterization of fatigue crack closure is an important objective because of its influence on fatigue crack propagation, particularly under conditions of variable amplitude loading. This paper describes a nontraditional technique for characteri

Richter's and Snoek's original works established the existence of an anelastic relaxation produced by a stress-induced interstitial reorientation in body-centered-cubic (bcc) metals. This anelastic relaxation, now referred to as a Snoek peak, has bee

Partial contact of two rough fatigue crack surfaces leads to transmission, reflection, diffraction and mode conversion of an acoustic signal at those contacts (asperities). This paper reviews recent experimental and theoretical efforts to understand

This paper deals with the basic mechanisms of fatigue damage in materials exposed to service and a series of nondestructive techniques for the early detection of this damage. For all materials with reasonably high fracture toughness it is the organiz

Strength determination of diffusion bonds by nondestructive evaluation is a necessity for the qualification of such bonds in critical components. We have applied ultrasonic techniques for a number of years and come to the following conclusions. There

Inconel 718 is a widely used material for applications at temperatures up to 650°C. Many research groups have studied the properties of Inconel 718 at different conditions [1, 2]. It is known that, after several thousand hours at 650 °C, Inconel 71

Most if not all materials undergo deterioration of their mechanical properties during service through one mechanism or another with eventual failure occurring due to this deterioration. As structures remain in service then, it becomes increasingly im
