Lesuer et. al., [7] evaluated the performance of the JC model by examining the large strain deformation response of 6061-T6 and Ti-6Al-4V with strain rates between 10-4 s-1 and 104 s-1. The strength and damage components of the JC model were then evaluated, and an improved model was developed and tested. This new model used the rate equations that represent the active deformation mechanisms during moderate to high rate loading. A second model was evaluated accounting for the influence of void formation on yield and flow behavior of a ductile metal …show more content…
Hlaváč, et. al.,[9] studied the use of abrasive water jet cutting of titanium and a titanium-niobium alloy. Hlaváč, et. al.,[9] compared experimental results with values from an earlier derived theoretical model. This earlier model studied the interaction between abrasive water jets and the material being cut using the limit values for transverse speed, depth of cut, and angle of cut. Hlaváč, et. al.,[9] studied the angle of striation on the walls of the cut created by the abrasive. They noted that the angle of striations was greater than the theoretical values for the lower transverse speeds. Hlaváč, et. al.,[9] suggested that the most probable cause was the influence of the slower, larger peripheral abrasive particles in the abrasive water jet layer. Although the results of the theoretical model matched well with the experimental results, when a correction to account for the increase of striation angle for low traverse speed was incorporated the model results showed an even better correlation [9]. Fan et. al., [10] described a new method to micro machine brittle material called micro abrasive water jet machining. The most important parameter for abrasive water jet machining is the rate of material removal. Fan et.al., [10] created a predictive mathematical model for the material removal rate for micro channel machining using
