The purpose of this paper is to present a solution for the peeling moment arising from the peeling stress distribution in any interface in a multilayer beam or plate. The solution is implemented for three- and four- layer beams; it is shown that it c

The peeling stress near the free edge of a bimaterial beam under uniform temperature change creates a moment which causes both layers to have identical curvatures at the interface. A new formula from beam theory is given for this Peeling Moment. A be

The determination of the peeling stress in the interface between the two layers of a bimaterial structure has long been of particular interest in the microelectronic industry. This is because peeling of deposited layers on silicon wafers, and delamin

This paper examines thermomechanical warpage in a bimaterial plate. It considers the suitability of axisymmetric and generalized plane strain finite element analyses, and it compares these to the 3-D analysis of a bimaterial plate in which properties

It has long been recognized that the properties of printed circuit boards and BGA laminates in the out-of-substrate direction differ greatly from the properties in the plane of the substrate. In this paper the variation of in-substrate-plane properti

The subject of this paper is a 14×22 mm ball grid array (BGA) integrated circuit assembly containing two or three chips. Three failure modes came to light in the reliability testing of this BGA package: delamination of solder resist from the top cop

Two-layer beams (i.e., bimaterials) under thermomechanical stress are prone to peeling or delamination at the free edges. The self-equilibrating peeling stress gives rise to a peeling moment Mp close to the free ends. A simple and exact formula for M
