Drawing Behavior of Solution Modified Polyethylene
International Polymer Processing, 1990Abstract The relationship between draw ability of high density polyethylene (HDPE) and entanglement density in the polymer has been studied by solution modifying the polymer. This involved precipitating the polyethylene from solutions in trichlorobenzene.

Exploration of polyelectrolytes as draw solutes in forward osmosis processes
Water Research, 2012The development of the forward osmosis (FO) process has been constrained by the slow development of appropriate draw solutions. Two significant concerns related to draw solutions are the draw solute leakage and intensive energy requirement in recycling draw solutes after the FO process. FO would be much attractive if there is no draw solute leakage and

An Analytical Solution of the Subsequent Drawing Force on Multistage Deep Drawing of Cylindrical Cup
Key Engineering Materials, 2019In multistage deep drawing process, the subsequent drawing force (SDF) is a key reference value, which plays a significant role on the practical die structure design. In the present study, an analytical calculation of the radial stress at the die exit as well as the SDF in cylindrical cup drawing process are proposed, considering the previous strain ...

Journal of Membrane Science, 2013
Abstract A model was developed for realizing the theoretically predicted performance of a forward osmosis (FO) system with an asymmetric membrane. The developed model has the capability to describe significant physical processes occurring in the FO system, such as reverse draw solute flux and internal (ICP) and external concentration polarization ...

On the complete solution of the deep-drawing problem
International Journal of Mechanical Sciences, 1968Abstract The paper presents the results of a complete analysis of the deep-drawing of a cylindrical cup, including the drawing and the stretch-forming parts. In the analysis, the strains due to drawing of the material initially situated near the die lip are first obtained and used as the boundary values for the analysis of the stretch-forming region.

A Solution to Bipartite Drawing Problem Using Genetic Algorithm
2011Crossing minimization problem in a bipartite graph is a well-known NP-Complete problem. Drawing the directed/undirected graphs such that they are easy to understand and remember requires some drawing aesthetics and crossing minimization is one of them. In this paper, we investigate an intelligent evolutionary technique i.e.

International Journal of Mechanical Sciences, 2014
Abstract An analytical solution for the estimation of the drawing force requested to perform a three dimensional drawing of a rectangular plate is presented. It has been developed using the limit analysis technique, on the basis of a three-dimensional velocity field, under the main assumptions of constant friction and perfect plasticity.

An eulerian elastoplastic FEM solution to drawing process
Journal of Materials Processing Technology, 1994Abstract An elastoplastic finite element method solution to drawing processes is presented. A steady state nature of these processes allows the problem to be formulated in the spatial reference frame. The solution is divided into two variational problems.
