Methodology and Applications of Mesoplasticity in Manufacturing Sciences

An improved strain gradient approach for determination of deformation localization and forming limit diagrams

“…It is the first time that people have ever been able to quantitatively explain the difference in the FLDs from in-plane and out-of-plane deformation. Lee and Yang (1993) presented a methodology and applications of mesoplasticity in manufacturing sciences. As it is explained in this reference, mesoplasticity emerges as a link between macroplasticity and microplasticity which introduces the essential microplasticity concepts to various intermediate scales and represents the connection between the continuum-based macroplasticity and atomistic physical theory of plasticity.…”

Variation of cutting forces in machining of f.c.c. single crystals

“…They assumed one slip system active continuously in each orientation setups. Micro-plasticity modelling of machining proposed by Lee et al [6][7] is another limited research available in the literature analysing a mechanism of single-crystal machining. Shirakashi et al [8] and Kota and Ozdoganlar [9] used the Bishop and Hill's crystal plasticity model to predict shear angles and specific energies for f.c.c.…”

“…Selecting materials for single-crystal machining studies, mainly copper and aluminium have been preferred in the literature [3][4][5][6][7][8][9][10][11][12]. In this paper a welldeveloped computational FE/SPH model was applied for these two monocrystalline materials to fully understanding the variation of cutting forces.…”
