Physical and numerical analysis of three dimensional extrusion process

Investigation into cold extrusion of aluminum billets using three-dimensional finite element method

“…Sofuoglu and Gedikli [8] simulated a three-dimensional extrusion process using physical modeling techniques and a finite element analysis (FEA) numerical method. Hambli [9] developed a finite element model which took into account the concept of failure probability to provide predictions for the occurrence of forming defects such as crack initiation and propagation during the manufacturing process.…”

A technical note on the role of process parameters in predicting flow behavior of plasticine using design of experiment

“…Plasticine, the most widely used soft modeling material, has been successfully used as a convenient model material to simulate the plastic deformation of metals as observed in many MFP for the last 40-50 years [5][6][7][8][9]. It is commercially available in various colors leading to different overall composition of each color from that of other ones.…”

Thermomechanical similarity between Van Aken plasticine and metals in hot-forming processes

“…If the appropriate modelling material is chosen through careful analysis, it can be used to predict many behaviours of the metal, such as the temperature, strain, and/or stress distributions [4]. Substantial research has been carried out to validate the use of plasticine to model material flow in metal-forming processes, such as extrusion, rolling, and forging [1,2,5,6]. Three-dimensional extrusion processes have previously been analysed with physical modelling and finite element analysis to validate the use of plasticine as a model for the behaviours of both elastic-plastic materials [2] and elastic-viscoplastic materials [5].…”
