RISNumerical 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 ...
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 ...
