In pre-stressed concrete structures, consideration is being given to replacing the steel tendons with CFRP rods. One of the challenges associated with this is to develop a suitable anchorage for the CFRP rods. A bonded anchorage was investigated, where the CFRP is potted in a steel tube using epoxy adhesive. Experimental static tests of different configurations were undertaken with failure occu...

Concrete patch repair has long been used to repair the damaged concrete structures. In cold regions, freeze– thaw cycle is one of the major damage factors. Not only the material itself is damaged by freeze–thaw cycles, but also the adhesive interface, which is regarded as the weakest part of composite system, degrades under freeze–thaw cycles. Air entraining agent has long been used to increase...

This paper investigates the role of material properties on crack path selection in adhesively bonded joints. First, a parametric study of directionally unstable crack propagation in adhesively bonded double cantilever beam specimens (DCB) is presented. The alternating crack trajectories in specimens of various material systems are simulated using the finite element method and the results indica...

Soft tissue adhesives are employed to repair and seal many different organs, which range in both tissue surface chemistry and mechanical challenges during organ function. This complexity motivates the development of tunable adhesive materials with high resistance to uniaxial or multiaxial loads dictated by a specific organ environment. Co-polymeric hydrogels comprising aminated star polyethylen...

Adhesion failure and/or detachment of ceramic tiling are common building defects. Bonding rupture of this type of coating presents a serious risk to people’s safety, in particular if it occurs on external façades. It may be avoided by earlier non-destructive inspections. This paper presents the results of an active thermography investigation in which adhesive bonding defects of ceramic coatings...
