1 Director: PhD. Raúl Gallard. El grupo de investigación está soportado por la Univ. Nacional de San Luis. y la ANPCyT. http://www.lidic.unsl.edu.ar/ The objective of this research is to develop a tool for the generation of 3D objects modeled with flexible materials, with visco-elastic or inelastic characteristics, similar to the plasticine. It is desirable to prioritize the simplicity of the i...

Abstract Central cracking refers to the formation of internal cavities in cross wedge rolling (CWR) products. It occurs various materials such as aluminium/titanium alloys, steels and plasticine at room or elevated temperatures, driven by different central mechanisms. However, these mechanisms are still elusive, a unified predictive model is absent due complex stress states within workpiece, in...

A re biotic interactions, such as competition and predation, stronger in the tropics than at higher latitudes? Biologists have long speculated that more intense interactions tend to occur at lower rather than at higher latitudes as a result of year-round warm and wet conditions near the equator, particularly in lowland tropical rainforests (1). This idea is now well established in the ecologica...

Forensic facial reconstruction aims at estimating the facial outlook associated with an unidentified skull specimen. Estimation is generally based on tabulated average values of soft tissue thicknesses measured at a sparse set of landmarks on the skull. Traditional 'plastic' methods apply modeling clay or plasticine on a cast of the skull, approximating the estimated tissue depths at the landma...

Coloured plasticine was used for making 3D anatomical and embryological plates with the aim of presenting an alternative method in teaching veterinary anatomy. Many selected anatomical illustrations representing muscles of the thoracic and pelvic limb of the horse, head muscles of the horse, ox, sheep and camel, some embryology diagrams including sperm structure, types of ova and cleavage were ...

The main objective of this research was to investigate the effect of material properties, strain-rate sensitivity, and barreling on the behavior of friction calibration curves. The compression tests were conducted to obtain the necessary material properties for the finite element analysis. A series of ring compression tests were then conducted in order to determine the magnitude of the friction...

Metal forming process simulation requires a very high cost including the cost for dies, machine and material and tight process control since the process involve very huge pressure. A physical modeling technique is developed and initiates a new era of educational tool of simulating the process effectively. Several publications and findings have shown a potential of the techniques else where. The...
