Computation of Power Dissipation Efficiency in Plastic Flow of Material Using Series Expansion Method | Original Article

ABSTRACT:

The efficiency of power dissipation (ij) is a criterion used by the metal architect for optimizing the efficiency of process and analyzing the metal forming problems like instabilities in a wide range of materials. Conventional way of obtaining the power dissipation is based on effective strain rate power law inculcating cubic spline method which is sometimes difficult to execute due to assumption of its piecewise continuity. The present article meets the expectation of obtaining the pon’er dissipation by modeling the effective stress of the series expansion method for defining the plastic deformation of the engineering work piece. This modeling phenomena is utterly expressible as a single formula unit and helps in resisting the superficial error due to inherent material defect in its bulk as well as the eiror causing due to sudden throb in applied physical conditions. Different graphical as well as numerical results shows that the maximum value of power dissipation efficiency at each process zone of strain is obtained at s = 0.001 & 773K temperature. Whereas, under the whole regime, the best efficiency correspond toe — 0.5, £• = 0.001, T -773K.
