In this research, we have studied the structural propenies of water. methanol and ethanol surrounding snidewalledcarbon nanotube (SWCNT) and mixed of them either and we have investigated the solvent effects onthe relative energies and dipole moment values by ming molecular dynamics simulation. We used differentforce field it, deterrnaned energy and other type of geometrical parameters, on the p...

Based on the cutting force theory, the cutting stress in end milling operation was predicted satisfactorily through simulation of using finite element method. The mechanistic force models were introduced in high accuracy force predictions for most applications. The material properties in the simulations were defined based on the cutting force theory, as a function of strain and strain rate wher...

in this paper, the direct extrusion process of bimetallic rods in conical dies is analyzed by an improved upper bound method. the deformation zone is subdivided into six smaller zones and by considering a non-spherical entrance boundary to the deformation zone, a velocity field is presented which is different from velocity fields employed in previous studies. the total power consumption of the ...

objective : tooth eruption has been a subject of extensive scientific studies; and literature is replete with different mechanisms of migration of a tooth from its bony crypt into the oral cavity. however, there is no common ground on the nature and source of the propelling force among the proponents of these theories. the purpose of this study was to explore the possibility of unifying the cur...
