this paper presents a novel formulation and numerical solutions for adhesively bonded composite joints with non-linear (softening) adhesive behaviour. the presented approach has the capability of choosing arbitrary loadings and boundary conditions. in this model adherends are orthotropic laminates that obey classical lamination theory. the stacking sequences can be either symmetric or asymmetri...

Adhesive bonding of aluminum holds some possible advantages over the traditional methods of construction in the aerospace industry. However, there is uncertainty about the mechanism of adhesive bonding and the changes occurring during environmental attack which reduce the bond strength. An improved understanding will aid in the development of better techniques for non-destructive testing (NDT) ...

The fatigue behaviour of single lap bonded joints under fatigue loading was already investigated and a suitable life prediction model was presented and validated [1-2]. The model is based on the actual damage evolution under fatigue load: a crack initiation followed by its propagation up to a critical length [2, 3]. In the present paper the evolution of fatigue damage in single lap joints is ex...

For developing novel fully biological materials, a central question is how we can utilize natural components in combination with biomimetic strategies ways that both allow feasible processing and high performance. Within this development, adhesives play role. Here, have combined two of nature’s excellent silk cellulose, to function as an adhesive system. As initial step processing, wood was del...

Peel tests are widely used to characterize the peel strength of bonded joints and control adhesion quality. There various configurations test, such as T-peel testing at 180°, floating roller climbing drum test. These methods have been mainly in aeronautical industry, a way assessing metallic joints. However, with growing use composite materials it is necessary these when subjected peeling loads...
