RISThermoelastic Stresses in Thick-Walled Vessels Under Thermal Transients via the Inverse Route
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A common threat to thick-walled vessels and pipes is thermal shock from operational steady state or transient thermoelastic stresses. As such, boundary conditions must be known or determined in ...
Thermoelastic Analysis of Thick-Walled Vessels Subjected to Transient Thermal Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A closed-form solution was derived for the transient thermal fields developed in thick-walled vessels subjected to a plausible exponential heating on the internal surface with convection to the ...
Thermoelastic Stresses in an Axisymmetric Thick-Walled Tube Under an Arbitrary Internal Transient
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A closed-form axisymmetric solution was derived for the transient thermal-stress fields developed in thick-walled tubes subjected to an arbitrary thermal loading on the internal surface with ...
Numerical Simulations of an Active-Stressing Technique for Delaying Fracture During Cutting of Alumina
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During a variety of high-speed cutting operations that can include both laser and traditional saw methods, full workpiece support is not always practical or even possible. As a result, costly ...
Active Stressing and the Micromanipulation of Stress-States for Delaying Fracture During Unsupported Laser Cutting
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During a variety of high-speed cutting operations that can include both laser and traditional saw methods, full workpiece support is not always practical or even possible. As a result, costly ...
Approximate Direct and Inverse Relationships for Thermal and Stress States in Thick-Walled Vessels Under Thermal Shock
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Approximate solutions were derived for the transient through steady-state thermal-stress fields developed in thick-walled vessels subjected to a potentially arbitrary thermal shock. In order to ...
Mode-I Stress-Intensity Factors for a Cracked Slab Under an Arbitrary Thermal Shock
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A stress intensity factor solution for a cracked slab subjected to an arbitrary thermal shock on one surface has been derived. As a first step, the transient temperature distribution was ...
Welding of Alumina Using a Pulsed Dual-Beam CO2 Laser
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Despite the many advantages of using lasers for welding ceramics (alumina in particular), cracks induced by the resulting and severe thermal stresses are often detrimental to weld quality and ...
An Inverse Method for the Determination of Thermal Stress-Intensity Factors Under Arbitrary Thermal-Shocks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The analysis of stress-intensity factors is of immense importance when designing vessels, pipes, and end-caps as well as supporting structures and plates seen in high-temperature applications. ...
Transient Surface Strains and the Deconvolution of Thermoelastic States and Boundary Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermoelastic states as they pertain to thermal-shock are difficult to determine since the underlying boundary conditions must be known or measured. For direct problems where the boundary conditions ...
