3D finite element modelling of drilling: The effect of modelling method

چکیده
A comprehensive benchmarking study has been carried out to determine the influence of mesh formulation and chip separation methods on reliability accuracy finite element modelling large diameter drilling operations. The Coupled Eulerian–Lagrangian updated-Lagrangian (with deletion) formulations available in ABAQUS/Explicit, together with re-meshing) DEFORM 3D are compared by simulating through-coolant AISI 1045. Johnson–Cook damage model was implemented a sub-routine ensure consistent is across formulations. Experimentally measured thrust force, torque, thickness values were used compare models performance assess predictions. dynamic re-meshing found be best performing methodology concerning predictions, whilst significantly under-predicted force torque. Due numerical instabilities computational cost, deletion method not recommended drilling.

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
3D Mesoscale Finite Element Modelling of Concrete
Concrete is non-homogeneous and is composed of three main constituent phases from a mesoscopic viewpoint, namely aggregates, mortar matrix, and interface transition zone (ITZ). A mesoscale model with explicit representation of the three distinctive phases is needed for investigation into the damage processes underlying the macroscopic behaviour of the composite material. This paper presents a f...

In this paper we present Gun3P, a parallel 3D finite element application that the Advanced Computations Department at the Stanford Linear Accelerator Center is developing for the analysis of beam formation in DC guns and beam transport in klystrons. Gun3P is targeted specially to complex geometries that cannot be described by 2D models and cannot be easily handled by finite difference discretiz...
متن کاملFinite-Element Modelling of Biotransistors
Current research efforts in biosensor design attempt to integrate biochemical assays with semiconductor substrates and microfluidic assemblies to realize fully integrated lab-on-chip devices. The DNA biotransistor (BioFET) is an example of such a device. The process of chemical modification of the FET and attachment of linker and probe molecules is a statistical process that can result in varia...
