Abstract Nowadays, polymeric materials are used in most industrial and engineering applications. In many of the applications, crack is initiated in mixed mode loading conditions. As a result, investigation of these materials at different loading angles is essential for safe design of structures. In this paper the mixed-mode elastic-plastic fracture behavior of ABS material based on J-integral key parameter was studied and the modified Arcan fixture was employed to investigate fracture behavior of this material under pure mode I (opening mode), pure mode II (shearing mode) and in plane mixed mode loading conditions. This work has been carried out experimentally by J–integral method named multi-specimen and normalization techniques. Finally, by fitting linear and power functions based on ASTM E813-81 and E813-87 test procedures respectively, the fracture toughness of this polymeric material was obtained in plane strain condition. The (J-R) curve comparison showed good agreement between the two methods. The minimum difference between the two methods obtained in a shear mode by ASTM E813-81 was about 1.37% and the maximum difference observed in tensile mode by ASTM E813-87 was about 30.7%.
