STRESS ANALYSIS OF COMPOSITE/METAL DOUBLE-SIDED BONDED JOINTS UNDER THERMO-MECHANICAL LOADS

Abstract

Abstract: A stress analysis model involving adhesive material nonlinearity under thermo-mechanical loading condition is developed to characterize adhesive stress distribution of composite/metal double-sided adhesively bonded joints. The maximum strain criterion is used to predict the initial failure of the adhesive based on the failure mode. The finite element analysis is conducted to validate the present closed-form solutions. The numerical results indicate that the analytical solutions and their simplifications correlate well with the nonlinear finite element computations. The present mathematical techniques and analysis approaches are critical to the successful design, analysis and implementation of bonded repairs.

Key words: thermo-mechanical loads, bonded joints, adhesive shear stress, analytical model, failure load
