For ̄ exible manufacture of a doubly curved sheet metal, a new sheet metal forming process is proposed that uses a movable punch set composed of two pairs of lower support punches and one upper centre punch. The process is characterized by ̄ exibility compared with the existing conventional processes because it does not require any complex-shaped die and the loss of material is minimized by unc...

Abstract The perspective of this paper is to characterize a Casson type Non-Newtonian fluid flow through heat as well mass conduction towards stretching surface with thermophoresis and radiation absorption impacts in association periodic hydromagnetic effect. Here also integrated the absorbing parameter. A time dependent fundamental set equations, i.e. momentum, energy concentration have been e...
