Finite element modelling of orthogonal cutting: sensitivity analysis of material and contact parameters

Sensitivity Analysis of Different Parameters Affecting Thermal Contact Conductance

In internal combustion engines, exhaust valve and its seat gain considerable temperature as the hot gases exit through them. So, the rate of heat transfer should be under control. In this study, the contact heat transfer coefficient has been estimated. An experimental study on an Air-Cooled internal combustion engine cylinder head has been considered. Using the measured temperatures of sensors ...

Modelling and Simulation of Metal Cutting by Finite Element Method

Finite Element Analysis of Hardened Steel Cutting

Hard machining, as attractive replacement for many rough and finish grinding operation, generates high cutting forces and temperature that enhance tool wear when act together. Therefore, the tool geometry and machining parameters have to be carefully optimized for a given material. Because of high cost and time consuming experimental work up-to-date advanced software for modeling and simulation...

Finite element analysis of nonsmooth contact

This work develops robust contact algorithms capable of dealing with complex contact situations involving several bodies with corners. Amongst the mathematical tools we bring to bear on the problem is nonsmooth analysis, following [14]. We speci cally address contact geometries for which both the use of normals and gap functions have difculties and therefore precludes the application of most co...
