Fracture Mechanics Analysis of the Durability of Resin-Bonded Bridge

The effect of Resin-Bonded Bridge Design Parameters on Crack Growth along Adhesive Layer

Abstract

The effects of resin-bonded bridge geometry on crack growth along the adhesive layer were analyzed by the use of elastic energy release rate g concept, together with the finite element technique. The values of g and the critical load for crack propagation in the adhesive layer are presented for various horizontal crack length a^*, safety factor n, and metal frame configuration and thickness t_m. Based on this analysis, suggestions for the design of resin-bonded bridge are suggested, in order to increase its durability.
