    Abstract

    Various special triangular and rectangular mixed finite elements for the static analysis of adhesive joints are presented. These finite elements take into account the continuity conditions at the interface, including the displacements and transverse stresses as variables, and they are developed for two-dimensional elastic behavior. Two processes have been developed to construct the finite elements through the use of Reissner's variational principle: the elimination process and the relocalization process.

    Several numerical examples are presented which illustrate the accuracy of the interface finite elements by comparison with the classical finite elements displacement method.

    Keywords:

    adhesive joints, interface stresses, mixed finite elements, continuity conditions, two-dimensional elasticity
