Abstract
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 possibility distributions for the displacements and shear stresses are depicted by graphics.
