Separation of delamination modes in composite beams with symmetric delaminations
Materials & Design, 2006Delaminated composite beam under general edge loading conditions is studied. Based on a technical engineering theory an analytical procedure for calculation of strain energy release rate and its separation into modes I and II of delamination is presented. By choosing a suitable displacement field based on second-order shear-thickness deformation theory

Advances in Delamination Modeling
2008Today’s microelectronic packages are typically composed of various materials, like silicon, metals, oxides, glues, and compounds (polymers). In Fig. 4.1, cross sections of a leadframe- and substrate-based package are depicted. Due to the dissimilar nature of these materials and the inherent presence of a large number of interfaces in each component ...

Effect of delamination angle on delamination energy
2000Different tests have been traditionally used to evaluate the delamination energy of paper and board. The values of delamination energy differ quite a bit. We propose that this is related to differences in the angle that opens between the delaminated faces of the specimen.

A delamination model for laminated composites is proposed. A damage variable takes into account the degradation of the adhesive properties of the interfaces. It is described by a nonsmooth, nonconvex functional [1].

Abstract Experience shows that the same types of delamination failures occur repeatedly, often when new coating systems are applied over old ones. The failures arise due to faulty specifications that fail to take into account the physics, chemistry and mechanical properties that govern coating behavior. Examples of this are given and the
