Prediction of Cutting Force in Bone Cutting Using Finite Element Analysis
Volume 1: Additive Manufacturing; Advanced Materials Manufacturing; Biomanufacturing; Life Cycle Engineering; Manufacturing Equipment and Automation, 2021Abstract In orthopedic surgery, bone cutting is an indispensable procedure followed by the surgeons to treat the fractured and fragmented bones. Because of the unsuitable parameter values used in the cutting processes, micro crack, fragmentation, and thermal osteonecrosis of bone are observed.

Metal Cutting Mechanics, Finite Element Modelling
2008This chapter presents a short analysis of the basics of traditional metal cutting mechanics, outlining its components and the basics of finite element modelling (FEM) of the metal cutting process. Based on a previously proposed definition of metal cutting, advanced metal cutting mechanics considers the power spent in metal cutting as the summation of ...

A Short Cut to Fuel Element Criticality Analysis
American Industrial Hygiene Association Journal, 1962Abstract This paper offers a method for estimating the number of elements required for criticality, with a uranium to zirconium weight ratio of from 1 to 10% and an enrichment of 93.5%.

Tissue Cutting Using Finite Elements and Force Feedback
2003This paper presents a methodology to simulate 3D cuts in deformable objects. It uses an explicit finite element approach to simulate deformations in real-time. We use a non-linear strain tensor formulation (Green tensor) to allow large displacements. Haptics is used to allow touching sensation of the cutting procedure.

Discrete Element Simulation of Coal Cutting
Applied Mechanics and Materials, 2014In order to study coal cutting mechanism, particle discrete element theory is adopted to establish numerical modeling of coal cutting processes. The paper presents a brief overview of the constitutive model and calibration of the discrete element model by simulation of the Uniaxial test and Brazilian tests and analyze the movement of picks. The results

Cut-off number of elements in polyadic Cantor arrays
2005 European Microwave Conference, 2005Discrete self-similar (polyadic Cantor) distributions of radiating elements allow the design of low side-lobe arrays. However, for achieving typical Tx-band geostastionary satellite requirements, we show here that such lacunar arrays may present a great number of elements compared to other types of aperiodic distributions deduced from genetic ...

Simulation of Cutting processes by the Particle Finite Element Method
GAMM-Mitteilungen, 2017AbstractThe cutting process is characterised by large deformations and large configurational changes. Especially the formation of chips and burrs pushes established modeling techniques to their limits. To overcome these difficulties, the particle finite element method (PFEM) combines the benefits of discrete modeling techniques and methods based on ...

Discrete Element Modelling of Rock Cutting
2011This paper presents numerical modelling of rock cutting processes. The model consists of a tool-rock system. 3D geometry is considered in the model. The rock is modelled using the discrete element method, which is suitable to study problems of multiple material fracturing like that of rock cutting.
