Prediction of Extrusion Pressure in Vortex Extrusion Using a Streamline Approach
Vortex extrusion (VE) is a severe plastic deformation technique which is based on the synergies between high strain accumulation and high hydrostatic pressure. Such a high amount of pressure, places a mandate to seek the method for investigation of the load under processing conditions. For this, kinematically admissible velocity field and upper bound terms based on Bezier formulation are develo...
متن کاملModelling of cold extrusion with experimental verification
This paper reports on an experimental and finite element analysis (FEA) of the cold extrusion of high-grade (AA1100) aluminium. The influence of die angle, reduction ratio and die land on the extrusion force during the extrusion process was investigated. A forward extrusion die was designed and manufactured for the purpose of the experimental research. Interchangeable elements of the extrusion ...
متن کاملNeural Modeling of Parison Extrusion in Extrusion Blow Molding
Back-propagation (BP) neural network is used to develop process models for the parison extrusion in extrusion blow molding based on experimental data. In applying the BP network, some modifications, such as using a self-adaptive learning rate coefficient, determining the number of hidden neurons through experimentation, and so on, to the original BP algorithm are carried out to speed up learnin...
متن کاملFreeform extrusion by sketched input
This paper presents a sketch based mesh extrusion method, which is useful for intuitive, efficient geometric modeling of freeform polygonal objects. With our method, the user can extrude either a closed or open surface from the surface or the boundary of a given mesh by sketched input. Thus, compared to earlier methods, our method provides more flexibility for solving surface modeling problems....
متن کاملStopping Spam by Extrusion Detection
End users are often unaware that their systems have been compromised and are being used to send bulk unsolicited email (spam). We show how automated processing of the email logs recorded on the “smarthost” provided by an ISP for their customer’s outgoing email can be used to detect this spam. The variability and obfuscation being employed by the spammers to avoid detection at the destination cr...
