Influence of Polymer Viscoelasticity on a Bending Bilayer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The bending bilayer technique is commonly employed to provide an empirical assessment of the often significant thermal stresses that develop in thin polymer films used in microelectronic packaging. ...
A Uniaxial Nonlinear Viscoelastic Constitutive Relation for Ice
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper concerns the description of uniaxial deformation and failure of ice in uniaxial compression in terms of a nonlinear viscoelastic constitutive theory. The constitutive model ...
Optimal Cooling Paths for a Class of Thermorheologically Complex Viscoelastic Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper concerns the optimal cooling of thin viscoelastic plates so as to minimize the residual thermal stresses upon completion of the cool-down process. The thermorheological behavior of ...
Some Implications of a Nonlinear Viscoelastic Constitutive Theory Regarding Interrelationships Between Creep and Strength Behavior of Ice at Failure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study explores several possibilities for a correspondence in the behavior of ice at failure during uniaxial creep (constant stress) and strength (constant strain rate) experiments. The usual ...
Optimal Cooling of Cross-Ply Composite Laminates and Adhesive Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper concerns the optimal cooling of symmetric, balanced, cross-ply composite laminates and adhesive joints so as to minimize the residual thermal stresses upon termination of the cool-down ...
Some Effects of Water Immersion on the Mechanical Behavior of a Polyimide Film
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Absorbed moisture is generally thought to have a plasticizing effect upon the mechanical behavior of polymers. This paper presents some experimental results illustrating the effects of water ...
Finite Element Viscoelastic Analysis of Temperature and Moisture Effects in Electronic Packaging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Several workers have demonstrated the presence of singular stress fields near the edge of a bimaterial interface subject to thermal gradients. Many of the analyses in the literature are limited ...
