This paper deals with the problem of General Shape Analysis. Simple shape measures based on a minimum bounding rectangle are investigated so as to obtain and compare general shape characteristics. The goal of General Shape Analysis is to find for each test object the one or few most similar templates. Thanks to this we can determine general information about a shape, such as how rectangular it ...

Preform design in forging processes is an important aspect for improving the forging quality and decreasing the production cost. The objective of this paper is to obtain an optimal perform shape in the consideration of the influence of the metal flow deformation in closed die forging process. Finite element method based DEFORMTM 3D software in conjunction with Taguchi method has been used to si...

Dieser Beitrag beschäftigt sich mit der Schaffung einer computergestützten Lösung für den Datenaustausch zwischen BUIS und Enterprise Ressource Planning (ERP)-Systemen am Beispiel SAP. Zunächst werden die relevanten Datenstrukturen und Schnittstellen des ERP-Systems erläutert und anschließend ein Softwareprototyp vorgestellt, der umweltrelevante Daten aus SAP ausliest und in dem in der PAS 1025...

In aluminum extrusion, a work-piece (billet) is pressed through a die with an opening that closely resembles the desired shape of a profile. By this process, long profiles with an enormous variety of cross-sections can be produced to serve different markets such as building, construction and transport industry. When the shape of a profile does not conform to the specifications defined by the cu...

the angle of repose of soil particles is an important factor for determining critical shear stress for initiation of soil particles motion during the erosion process. there are different methods for measuring the angle of particle repose and the result of each method is somewhat different from those of the others. sliding and fixed-base piling methods are the two most common methods in the lite...

In this paper, the mechanism of improvement of formability in pulsating hydroforming of T-shape tubes is investigated by the finite element simulation and experiment. It is shown that local thinning was prevented by oscillating the internal pressure, because the protrusion is formed gradually by the prevention of sharp bulging. In the hydroforming, for the pulsating pressure, several steps occu...
