RISDie Cracking at Solder (In60-Pb40) Joints on Brittle (GaAs) Chips: Fracture Correlation Using Critical Bimaterial Interface Corner Stress Intensities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We study cracking from the interface of an In60-Pb40 solder joint on a brittle GaAs die when the joint is subjected to a uniform temperature change. Our primary objective is to apply and ...
Tetragonal Phase Transformation in Gold Nanowires
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: First principle, tight binding, and semi-empirical embedded atom calculations are used to investigate a tetragonal phase transformation in gold nanowires. As wire diameter is decreased, tight ...
Micro and Macro Deformation of Single Crystal NiTi
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present experimental results on the instrumented Vickers micro-indentation and compression of solutionized Ni-rich NiTi single crystals. The tests are conducted at room temperature where the ...
Constitutive Modeling of Shape Memory Effects in Semicrystalline Polymers With Stretch Induced Crystallization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Polymers can demonstrate shape memory (SM) effects by being temporarily fixed in a nonequilibrium shape and then recover their permanent shape when exposed to heat, light, or other external ...
Application of A Microstructural Constitutive Model of the Pulmonary Artery to Patient-Specific Studies: Validation and Effect of Orthotropy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We applied a statistical mechanics based microstructural model of pulmonary artery mechanics, developed from our previous studies of rats with pulmonary arterial hypertension (PAH), to patient-specific ...
