EFFECTS OF ADHESION ON THE EFFECTIVE YOUNGS MODULUS IN GLASS SLIDE GLUE LAMINATES .2. ANALYSIS

In Part I of this study we experimentally explored the effects of adhe sion area, number of glue spots, and bond thickness on the effective Y oung's modulus in glass slide/glue composite specimens having adhesion areas ranging from 0%-100%. In this paper, the Young's modulus data a re analysed further as a function of bond thickness in glass slide/glu e laminates having 100% adhesion area and are compared with prediction s from two existing models, a rule of mixtures model and a dynamic bea m vibration model. Based on the experimental results obtained in Part I, a model has been obtained for glass slide/glue composite specimens by applying several boundary conditions. The resulting expression pred icts the elastic modulus of a three-layer composite specimen bonded by an adhesive. The model developed describes well the experimental resu lts obtained in Part I.
