Abstract

Estimation of adhesive bond strength in laminated safety glass samples, ie windshields, has been carried out using a multilayered guided wave model and validated using attenuation measurements. As in Part 1 of this study, the interfaces are treated as imperfect interfaces and modelled as beds of longitudinal and shear springs. The spring constants are estimated using fracture mechanics in conjunction with surface analysis of the plastic interlayer and glass plates via atomic force microscopy and profilometer measurements. Using the multilayered guided wave model, it was observed that the S1 mode exhibits periodic attenuation peaks in specific frequency, ranges, and that the attenuation of these peaks is sensitive to the interface adhesion levels. The mode shapes and power flow profiles corresponding to these peaks are presented and discussed. Experimental attenuation measurements' taken on the same laminated safety glass test samples discussed in Part I are presented and discussed to validate the theoretical predicted attenuation values using this multilayered model.
