The Fuzzy Finite Element Stress Analysis of Adhesive-Bonded Single Lap Joints

An adhesive-bonded single lap joint is analyzed using a new fuzzy finite element model. In the model, Young’s moduli and Poisson’s ratios of the joint materials are taken as fuzzy numbers in order to take the uncertainty of the material properties into account. The fuzzy numbers are modeled using linear triangular membership functions. At a selected material point in the adhesive layer, the pos...

Cohesive Zone Modeling of Mode I Fracture in Adhesive Bonded Joints

This paper deals with the application of Cohesive Zone Model (CZM) concepts to study mode I fracture in adhesive bonded joints. In particular, an intrinsic piece-wise linear cohesive surface relation is used in order to model fracture in a pre-cracked bonded Double Cantilever Beam (DCB) specimen. Finite element implementation of the CZM is accomplished by means of the user element (UEL) feature...
