5. Conclusions In this research the ability of Bi-ASB test specimen to produce any desired deformation of mode I and mode II was proved using several finite element analyses. Due to some advantages such as, simple geometry, modular design of sample for easily producing different mode mixities, small size of sample and ease of test setup compared to conventional test samples, the Bi-ASB sample can be proposed as suitable test candidate for fracture studies of adhesively bonded joints under in-plane loading conditions. The presented fracture parameters (obtained using several finite element analyses and for different geometrical, material and loading conditions) allow the researchers to utilize this specimen for determining the load carrying capacity and analyzing the ABJs made of Bi-ASB test specimen.
