Dynamic Fracture Under Normal Impact Loading of the Crack Faces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Results of experiments on crack-face impact are presented. The transient stress-intensity factor variation of a crack has been traced by the Stress-Intensity Factor Tracer (SIFT) [1] under ...
A Stress Intensity Factor Tracer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new optical method, Stress Intensity Factor Tracer (SIFT), has been developed. The device measures continuously the real-time stress intensity factor variation, K1 (t), of a moving crack tip ...
Pressure-Shear Impact of 6061-T6 Aluminum
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental results are presented for impact of two parallel plates of 6061-T6 Aluminum, skewed at an angle of 26.6° from the axis of the projectile. A transverse displacement interferometer ...
Experimental Study on Electric-Current Induced Damage Evolution at the Crack Tip in Thin Film Conductors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The time dependent temperature distribution induced by electric current heating in a double edge cracked, unpassivated thin aluminum or gold film interconnect lines is monitored using a high ...
Hygroscopic Effects in Aramid Fiber/Epoxy Composite
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hygroscopic effects in aramid fiber composites are assessed semi-empirically using a combination of micromechanics models and experimental data. It is pointed out that the in situ moisture ...
Characterization of Elevated Temperature Crack Growth in Hastelloy-X Using Integral Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Linear elastic fracture mechanics approaches are not suitable for prediction of fatigue crack growth in the nonlinear regime at elevated temperatures. The objective of this paper is to investigate ...
On the Calculations of the Stored Energy of Cold Work
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When a metal deforms plastically, most of the mechanical energy expended in the deformation process is converted into heat and the remainder is stored in the material. A method for the ...
Multiaxial Fatigue Under Variable Amplitude Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multiaxial fatigue under variable amplitude loading is investigated using Kandil et al.’s parameter, rainflow cycle counting on the shear strain history, and the Miner-Palmgren damage rule. Fatigue ...
Viscoelastic Circular Plate Wave Guide Absorber
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A waveguide absorber removes and dissipates vibrational energy from a structure by traveling waves. The performance of a wave guide absorber is determined by the driving point impedance. In ...
Erratum: “The Buckling of an Elastic Layer Bonded to an Elastic Substrate in Plane Strain” (Journal of Applied Mechanics, 1994, 61, pp. 231–235)
