RISStress-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 ...
Application of the Cosserat Spectrum Theory to Stokes Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an application of the Cosserat spectrum theory in elasticity to the solution of low Reynolds number (Stokes flow) problems. The velocity field is divided into two components: ...
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 Format Method for Generating Liapunov Functions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method is developed for generating Liapunov functions, V, which have the property that, along the trajectories of a system under consideration, the scalar functions V̇ or (V̇ − Vt ) take ...
Fiber-Reinforced Membrane Models of McKibben Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A McKibben actuator consists of an internally pressurized elastic cylindrical tube covered by a shell braided with two families of inextensible fibers woven at equal and opposite angles to the ...
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 ...
Scattering of Ultrasonic Wave by Cracks in a Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A hybrid numerical method combining finite elements and the boundary integral representation is used to investigate the transient scattering of ultrasonic waves by a crack in a plate. The ...
