In this paper, the use of a cohesive-zone approach to model the mode-I fracture of adhesive joints made from a polymer-matrix composite is demonstrated. Cohesive-zone parameters were obtained by matching numerical results to experimental observations. It is shown that there is a distinction between the characteristic strength of the interface associated with the toughness, and the intrinsic coh...

DC electric potential technique has been used to monitor crack growth in conductive materials. A constant DC current is passed through these materials and the crack length is measured through the changes in the electrical voltage at the crack mouth. However, this method is not applicable in crack growth measurement in nonconductive materials or adhesively bonded joints. For these materials, a n...

Glass fiber-reinforced composites are commonly employed as structural materials in many fields. In addition, glass frequently used with metals, particularly the automotive and aerospace industry. this context, tensile strengths of simple hybrid single-lap joints having similar (i.e., aluminum/aluminum composite/composite) dissimilar aluminum/composite) plates were investigated experimentally st...
