چکیده
Polymer matrix composites reinforced with graphene derivatives are receiving increasing attention in academia and industry. For future applications, however, the machinability of these materials needs to be understood. This study introduces cutting mechanism nanoplatelet (GNP)-reinforced polymer using finite element (FE) method, where process is investigated terms stress distribution, chip formation, surface morphology. The results show that machined polymer/GNP material has more defects compared plain presence GNPs influences profiles. Small cavities/cracks can found about 40% area epoxy/GNP, while no small on epoxy. machining conditions epoxy/GNP should selected such a way removal deformation falls regime without viscoplastic scaling/tearing brittle cracking. model for validated experiments.

Experimental and Finite Element Analyses of the Hydrostatic Cyclic Expansion Extrusion (HCEE) Process with Back-Pressure
It is generally known that severe plastic deformation processes with back pressure not only apply higher hydrostatic stress and more deformation compared to what a regular process can apply to a workpiece but also prevent surface defects in the workpiece during the process. Hydrostatic cyclic expansion extrusion (HCEE) was developed recently for processing long ultrafine-grained metals and allo...
