Abstract: A hole which is plastically expanded and then allowed to contract is referred to as coldworked. The residual strains around holes which were coldworked by an industrial process were measured ...

Abstract: A compressive pulse applied to the base of a cone develops a tensile tail as it propagates toward the cone apex. This tension can cause fracture of the cone perpendicular to the cone axis ...

Abstract: Biaxial principal strains were measured at the roots of notches in aluminum specimens with a laser-based interferometric technique. Interference patterns from three tiny indentations spaced 150 ...

Abstract: Biaxial strains were measured at the roots of single notches in zirconium alloy specimens under loading and creep conditions (up to 1200 hours) at 250°C. A laser-based interferometric ...

Abstract: Coldworking the material near the edge of a fastener hole is one important means of increasing fatigue life. The stresses, strains, and location of the boundary between elastic and plastic ...

Abstract: It has been proposed in the literature that the Neuber relation be modified to read Kε/Kt × (Kσ/Kt)m = 1 in order to improve its predictive capability when plane strain loading conditions ...

Abstract: A preceding paper reported the results of biaxial strain measurements at the roots of notched aluminum specimen subjected to monotonic tension loading. The specimens had different amounts of ...

Abstract: A straightforward procedure is demonstrated for measuring local cyclic elastoplastic biaxial stresses at notch roots. First, the biaxial cyclic strains are measured over short gage lengths (150 ...

Abstract: The problem of a finite-width tension specimen containing a crack oriented at various angles to the load axis is attacked from experimental and theoretical viewpoints. Displacements of an ...
