The assessment of the influence of the work-hardening of material on the optimum die profile and drawing force  in rod drawing process is the main objective of the present paper. The upper bound solution, based on the assumption of perfect plasticity, has been extended to consider the work-hardening of the material during the rod drawing process through curved dies. Analytical results of drawin...

In this paper, rod drawing process of strain-hardening materials is investigated by analytical, numerical and experimental methods. The classic upper bound solution, based on the assumption of perfect plasticity, has been extended to consider the work-hardening of the material during the drawing process. For a given process conditions and mechanical properties of the rod material, the power ter...

The wire drawing process is extensively used in manufacturing components such as rivet, screw, welding wire, etc. In this work, an analytical of the wire drawing process has been considered for two-stage operation. ABAQUS commercial Finite Element code has been used to obtained the drawing force. Then, The analytical and experimental results been compared. The results show a good agreement for...

Recent empirical research has indicated that human graph reading performance improves when crossing angles increase. However, crossing angle has not been used as an aesthetic criterion for graph drawing algorithms so far. In this paper, we introduce a force-directed method that aims to construct graph drawings with large crossing angles. Experiments indicate that our method significantly increa...

ForceAtlas2 is a force vector algorithm proposed in the Gephi software, appreciated for its simplicity and for the readability of the networks it helps to visualize. This paper presents its distinctive features, its energy-model and the way it optimizes the “speed versus precision” approximation to allow quick convergence. We also claim that ForceAtlas2 is handy because the force vector princip...

Many automatic graph layout algorithms can cause shaped vertices and edge labels (which have a size when drawn on the screen) to overlap in the resulting visualisation. Overlaps can hide information that users expect to see in cases where the graph is small. We perform two experiments on a large real-world set of small (10-110 vertex) graphs to compare how different combinations of forces in Ea...

A potential field approach, coupled with force-directed methods, is proposed in this paper for drawing graphs with nonuniform nodes in 2-D and 3-D. In our framework, nonuniform nodes are uniformly or nonuniformly charged, while edges are modelled by springs. Using certain techniques developed in the field of potential-based path planning, we are able to find analytically tractable procedures fo...

The adoption of the stress-majorization method frommulti-dimensional scaling into graph layout has provided an improved mathematical basis and better convergence properties for so-called “force-directed placement” techniques. In this paper we give an algorithm for augmenting such stress-majorization techniques with orthogonal ordering constraints and we demonstrate several graphdrawing applicat...

in this paper, a novel technique on friction aided deep drawing using tapered blank holder divided into eight segments is proposed to overcome defect of friction aided deep drawing using four segments tapered blank holder technique. a taper blank holder is designed to be of two parts: stationary part with 5 degree taper angle and moving parts divided into eight tapered segments. the main functi...
