Stress-Corrosion Cracking and the Interaction Between Crack-Tip Stress Field and Solute Atoms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on the elastic interaction between a solute atom and a tensile crack-tip stress field, a mechanism of stress-corrosion cracking was proposed and analyzed. This elastic interaction provides ...
Crack Propagation in Thin Metal Sheet Under Repeated Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental and analytical investigation was undertaken to study the fundamental factors of crack propagation in a thin metal sheet under repeated axial loading. Sheet specimens of 2024-T3 ...
Fatigue Crack Propagation and Applied Stress Range—An Energy Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Using the saturation of hysteresis energy absorption as a criterion for fatigue crack propagation, the rate of crack propagation in a thin and wide metal sheet under repeated axial loading is ...
Fatigue Crack Growth Under General-Yielding Cyclic-Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In low cycle fatigue, cracks are initiated and propagated under general-yielding cyclic-loading. For general-yielding cyclic-loading, Dowling and Begley have shown that fatigue crack growth rate ...
The Role of Three-Dimensional Effects in Constant Amplitude Fatigue Crack Growth Testing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An accurate knowledge of the dependence of the fatigue crack growth rate (da/dN) on the stress intensity factor range (ΔK) is necessary to perform a safety analysis of any structure. Fatigue ...
A Design Approach for Correlating High Temperature Fatigue Crack Growth Over a Wide Range of Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High temperature fatigue crack growth was studied in several materials under various environmental conditions. At temperatures less than one-half of the melting point, creep effects were found ...
Analytical Solutions for One-Dimensional Water Flow in Vegetated Layered Soil
Publisher: American Society of Civil Engineers
Abstract: Vegetation reduces soil pore-water pressure (PWP) through root water uptake. There are limited studies about the effects of vegetation on PWP distributions in layered soil, such as multilayered earthen landfill cover. New ...
A New Method and Instrument for Measuring In Situ Gas Diffusion Coefficient and Gas Coefficient of Permeability of Unsaturated Soil
Publisher: American Society of Civil Engineers
Abstract: A new method and instrument were developed for in situ measurement of the gas diffusion coefficient (Dg) and gas coefficient of permeability (kg) of unsaturated soil. Air containing tracer gas of volumetric concentration ...
Effects of Pore-Size Distribution on the Gas Diffusion Coefficient and Gas Permeability of Compacted Manufactured Sand Tailing–Bentonite Mixtures
Publisher: ASCE
Abstract: Gas permeability (ka) and gas diffusion coefficient (Dp) are vital for controlling gas transport through earthen landfill cover overlying municipal solid wastes or acid mine tailings. Soil clods generated during the ...
A New Method for Simultaneous Measurements of Gas Dispersion Coefficient and Gas Coefficient of Permeability of Unsaturated Soils
Publisher: ASCE
Abstract: This study developed a new method to simultaneously measure gas dispersion coefficient and gas coefficient of permeability (GCP) of an unsaturated soils with due theoretical consideration of steady-state gas transport ...
