Artigo Determination of the mechanical behaviour of a ceramic glass composite by finite element method(International Journal of Research and Reviews in Applied Sciences, 2012-11) Miranda, Jader dos Santos; Christoforo, André Luís; Dias, Avelino Manuel da SilvaThe constant advances in the industry originate from the need to develop solutions for a variety of applications. Mechanical Engineering has introduced innovations with regard to the science of materials subjected to various efforts. Recent studies demonstrate the potential of some classes of materials, special emphasis on ceramics. In this paper we are going to study primarily the ceramic glass sub-class through analysis of Zerodur®. Zerodur® is trade name given to an inorganic material with low thermal expansion, widely used in equipment subjected to large temperature variations, where is necessary to maintain good shape and geometry precision. It has high surface hardness and hence fragility when subjected to tensile. In order to enhance the mechanical characteristics of Zerodur® is proposed to merge the same with other materials (composite). With the aid of finite element method makes it possible to analyze the global behaviour of the composite when subjected to external stresses. In this paper we used the commercial finite element solver MARC™ on numerical analysis of computational structures Zerodur® - Steel. The main objective of this work is to simulate the behaviour of the composite test by three point bending. Subsequently, we intend to analyze the mechanical stiffness and implement models with crack strain.
