Abstract: 
ABS (Acrylonitrile butadiene styrene) polymeric material is widely used in different industries. The increasing demand of ABS for different applications has required a thorough understanding of its fracture behavior. This paper investigates mixed-mode fracture behavior of ABS polymeric material based on experimental and numerical analyses. Experiments were conducted on modified Arcan set-up. By varying the loading angle from 0° to 90°, pure mode-I, pure mode-II and a wide range of mixed-mode data were obtained experimentally. Also, finite element analysis was carried out for different loading conditions in order to determine correction factors needed for fracture toughness calculations. In this study viscoelastic behavior was considered for ABS specimens. Therefore, it is expected that the values of stress intensity factors to be time (frequency) dependent. Consequently, based on correspondence principle and assuming linear elastic fracture mechanics, time dependent mixed-mode fracture toughness for ABS polymeric material was determined. Results indicated that in all loading conditions, values of fracture toughness decrease while time increases in stress relaxation test, until a specific time. Accordingly, it can be resulted that the minimum value of fracture toughness of ABS, which plays a crucial role in various applications, does not appear in the first instance of loading.
