Crystal plasticity finite element modeling and simulation of diamond cutting of polycrystalline copper

Journal of Manufacturing Processes, 2019
Microstructural-related deformation behavior leads to anisotropic machining characteristics of polycrystalline materials. In the present work, we develop a crystal plasticity finite element model of ultra-precision diamond cutting of polycrystalline ...

Finite Element Peen Forming Simulation

2012
Shot peening consists of projecting multiple small particles onto a ductile part in order to induce compressive residual stresses near the surface. Peen forming, a derivative of shot peening, is a process that creates an unbalanced stress state which in turn leads to a deformation to shape thin parts.

Finite Element Simulations of Polycrystals

Computational Material Modeling, 1994
Abstract The finite element method provides a flexible and powerful framework in which polycrystal plasticity theory may be implemented. The relative sizes of crystals and elements may span orders of magnitude: elements may be small or large compared to crystals. When they are large the finite element discretization is of a continuum,

Finite Elemente Simulation

2019
Die Belastungsrandbedingung bei der numerischen Berechnung der durchgefuhrten Kopfaufprallversuche wird uber ein detailliertes FE–Modell des Kopfimpaktors aufgebracht. Um eine moglichst realitatsnahe Abbildung des mechanischen Verhaltens und somit eine reprasentative Prognose der fur den HIC–Wert masgebenden Beschleunigungskomponenten zu gewahrleisten,

Fast Finite Elements for Surgery Simulation

1997
This paper discusses volumetric deformable models for modeling human body parts and organs in surgery simulation systems. These models are built using finite element models of linear elastic materials. To achieve real-time response condensation has been applied to the system stiffness matrix, and selective matrix vector multiplication has been used to ...

Elasto-Plastic Finite Element Simulations

2014
The continuum mechanics basics for plasticity, i.e. the yield condition, the flow rule, the hardening law, and the elasto-plastic modulus, for the one-dimensional rod will be used to describe the elasto-plastic behavior for monotonic and cyclic loading.

Finite Element Simulations of Twisted NbTi Conductors

IEEE Transactions on Applied Superconductivity, 2013
Low-temperature superconducting wires, NbTi and Nb3Sn, designed for ac applications, such as CERN and ITER magnets, are composed of twisted multifilament structures. Under time-varying applied magnetic field, twisting decreases the induced electromotive forces between the filaments and is therefore an effective method to reduce interfilamentary ...

Finite-element simulation of solidification

Journal of Materials Processing Technology, 1990
Abstract The problem of predicting the solidification front and the temperature field for the case of the continuous-casting process is of great practical importance. Due to the release of latent heat during the change of phase, such a problem is non-linear and considerably more difficult to solve than the corresponding single-phase problem.
