RISOn the Proper Boundary Conditions for a Beam
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Employing the asymptotic expansion approach, the boundary conditions of a beam are reconsidered in the present paper. Gregory and Wan’s (1984) decay analysis technique is extended here to formulate ...
On the Derivation of a Refined Theory for Nonhomogeneous Anisotropic Shells of Revolution
Publisher: The American Society of Mechanical Engineers (ASME)
Discussion: “A Review on the Analysis of Laminated Shells” (Kapania, R. K., 1989, ASME J. Pressure Vessel Technol., 111, pp. 88–96)

The Effect of Cooling Rate on the Growth of Cu-Sn Intermetallics in Annealed PBGA Solder Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the diffusion behavior and microstructural evolution of Cu-Sn intermetallics at eutectic Sn-Pb solder/copper substrate interface of PBGA solder joints was studied. The PBGA solder ...
Competition Between Fatigue Crack Propagation and Wear
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on a semi-empirical derivation of the Paris fatigue law, the fatigue crack length a is related to the yield limit or flow stress, which ultimately is related to the hardness of the ...
Fatigue Lifetimes of PBGA Solder Joints Reflowed at Different Conveyor Speeds
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The shear cycle fatigue lifetimes of plastic ball grid array (PBGA) solder joints formed using different reflow profiles are studied in this paper. The profiles were devised to have the same ...
Beam Theory and Its Suitability for the Analysis of Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of the asymptotic expansion technique when applied to the three-dimensional elasticity equations is outlined and used to demonstrate the development of an asymptotic beam theory and ...
