An Upper Bound Analysis of Sandwich Sheet Rolling Process
In this research, flat rolling process of bonded sandwich sheets is investigated by the method of upper bound. A kinematically admissible velocity field is developed for a single layer sheet and is extended into the rolling of the symmetrical sandwich sheets. The internal, shear and frictional power terms are derived and they are used in the upper bound model. Through the analysis, the rolling ...
متن کاملAn Upper Bound Approach for Analysis of Hydroforming of Sheet Metals
Considering a kinematical velocity admissible field, the upper bound method has beenused for predicting the amount of pressure in hydroforming of sheet metals. The effects of workhardening, friction and blank size have been considered in pressure prediction. Also the effect ofsheet thickness variation has been considered in the present work formulations. The relation betweenpressure and punch s...
متن کاملThree - Dimensional Shape Description Using
Blum's transform, variously known as the symmetric axis transform, medial axis transform, or skeleton, and his associated two-dimensional shape description methodology are generalized to three-dimensions. Bookstein's twodimensional algorithm for finding an approximation to the symmetric axis is also generalized. The symmetric axis (SA) of an object with a smooth boundary is the locus of points ...
متن کاملA generalized upper bound solution for bimetallic rod extrusion through arbitrarily curved dies
In this paper, an upper bound approach is used to analyze the extrusion process of bimetallic rods through arbitrarily curved dies. Based on a spherical velocity field, internal, shearing and frictional power terms are calculated. The developed upper bound solution is used for calculating the extrusion force for two types of die shapes: a conical die as a linear die profile and a streamlined di...
