COMPOSITE SHAPE MEMORY ALLOYS USED IN ENERGY DISSIPATION APPLICATIONS
Journal Title: TEHNOMUS - Year 2011, Vol 18, Issue 1
Abstract
The paper presents some detailed technical solutions to design an equipment for ice parts Rapid Prototyping. The authors designed two alternative solutions of the equipment applying a methodology developed within the TCM Department of the POLITEHNICA University of Bucharest. Both alternative solutions are based on the operation principle of selective freezing with liquid nitrogen of water sprayed on the working surface according to section image conveyed by computer by slicing a CAD model. The article focuses on the methods of solving several issues of conception, design and achievement of the high complexity equipment.
