Modelling and Simulation of Metal Cutting by Finite Element Method

Image processing and Finite Element modelling for analysis of a metal matrix composite

Finite element analysis is the most used methodology to predict the mechanical behavior of a large spectrum of materials. It covers many research areas. In the case of metal matrix composites the reinforcing particles are being approximately represented by general regular geometries; i.e. spherical, rectangular, cylindrical and pyramidal shapes. Their distribution is generally arbitrary or appr...

Dimpling process in cold roll metal forming by finite element modelling and experimental validation

The dimpling process is a novel cold-roll forming process that involves dimpling of a rolled flat strip prior to the roll forming operation. This is a process undertaken to enhance the material properties and subsequent products' structural performance while maintaining a minimum strip thickness. In order to understand the complex and interrelated nonlinear changes in contact, geometry and mate...

Thermomechanical modelling and force analysis of friction stir welding by the finite element method

Friction stir welding (FSW) is a solid-state jointing technology, in which the butted plates are heated, plasticized and jointed locally by the plunged probe and shoulder moving along the joint line. The residual stresses due to the thermomechanical performance of the material and the constraint of the welded plates by the xture are one of main concerns for this process. A prediction of the cla...

Layered Manufacturing of Thin-walled Parts

We describe a new algorithm we have developed for making partially hollow layered parts with thin, dense walls of approximately uniform thickness, for faster build times and reduced material usage. We have implemented our algorithm on a fused deposition modeling (FDM) machine, using separate build volumes for a loosely filled interior and a thin, solid, exterior wall. The build volumes are deri...
