Nguyen, N., Hosseini, A.* (2023): Direct Calculation of Johnson-Cook Constitutive Material Parameters for Oblique Cutting Operations. Journal of Manufacturing Processes. 92: 226-237.

Characteristics and behaviors of materials during manufacturing processes highly depend on their mechanical properties and microstructures. However, these characteristics and behaviors can be greatly influenced by other factors such as strain, strain rate, and temperature during the process. The Johnson-Cook (J-C) constitutive material model has been extensively used to describe the material behavior under such circumstances. The J-C parameters are usually determined using the Split Hopkinson Pressure Bar (SHPB) test which is time consuming and costly...

Application of additively manufacturing (AM) metals is growing rapidly; however, post-process finish machining is still required to improve dimensional accuracy and surface quality. Determining the high-strain high-temperature behavior of AM metals is critical in simulating finish machining, designing appropriate cutting tools, and predicting surface integrity. This paper investigated the machining characteristics of AM Ti-6Al-4V produced using powder bed fusion. High-strain high-temperature behavior of AM Ti-6Al-4V was determined numerically and used in simulating the process...
