A Novel Finite Element Approach to Modeling Hard Turning in Due Consideration of the Viscoplastic Asymmetry Effect

Abstract: A novel material model for strain rate and temperature dependent asymmetric viscoplastic deformation behavior considering transformation induced plasticity (TRIP) as a crucial phenomenon influencing the hard turning process-oriented ductility was developed. Within the framework of viscoplasticity and continuum damage mechanics, the well-established Johnson-Cook flow stress model has been upgraded by the concept of weighting functions accounting for the asymmetric viscoplastic material behavior under different … Show more

“…Among all the manufacturing processes, also machining operations must respect these upgrading restrictions, and due to the development of superabrasive cutting tool materials, hard turning has been rapidly developed as an affordable answer [2]. Hard turning is defined as the cutting of materials with a hardness higher than 45 HRC [3], and it represents a profitable alternative to conventional grinding process [4]. Compared to this latter, hard turning is capable to produce better surface finish and accuracy at higher material removal rates [5].…”
