Abstract text:
This paper presents the outcomes of analytical and numerical investigations regarding the behavior of double lap shear joint composed of pultruded GFRP profiles and structural epoxy adhesive. The shear and the peeling stresses along the bond length have been evaluated and graphically plotted. Specific points at the top interface between the adhesive and the GFRP composite elements were established in order to closely record the stress and strain variations. The ultimate values and the patterns of the graphical distributions of the stresses indicates that the shear and the peeling stresses obtained by analytical methods are in good agreement with those calculated by numerical methods, except for the peak values near the free edge of the bond length.
Key Words:
adhesively bonded joints; double lap shear joint; finite element modelling; analytical model; GFRP composite elements
