Strain Energy Release Rate of Double Cantilever Beam Specimen with Finite Thickness of Adhesive Layer

Strain energy release rate G_I of DCB-FTAL (Double Cantilever Beam with Finite Thickness of Adhesive Layer) specimen was determined so as to include some variables as thickness and flexibility of adhesive layer and sizes and mechanical properties of adherend. For sharp crack case, the derived equation of GI was compared with previous results, on the other hand, in case of thick adhesive layer, the derived equation of compliance C was compared with experimental results. Fracture Toughness G_ of DCB-FTAL specimen (Buna-Epoxy, EP-60 system) was also determined, and obtained results were discussed together with previous results.
