Using sand moulds for step-shape casting tests and different silicon percentage of nodular cast iron it was possible to separate structural variations produced during freezing from those occurring at Ac1 transformation temperature. The results show that an increase in silicon content leading to different variation in the matrix structure> leads to a changing mechanical properties of nodular cast irons. Tensile strength and elongation of obtained as-cast nodular cast iron with the composition of 3.9%C, 3.2%Si, 0.5%Mn are maximum of about 524.5N/mm2 and 19.8% accordingly. In the same nodular cast iron, but only with 0.1% Mn the silicon addition first increases after decreases elongation, impact toughness and hardness. But tensile strength changes to the opposite side

Reasons for simulation being underutilized • Simulation modeling is a time-consuming and knowledge/information intense process • Most models developed are customized “rigid” models that cannot be reused or easily adapted to other even similar problems (Arons 1999, 2000; Zhou 2004) • Conceptual modeling is a critical step that directly affects the quality and efficiency of simulation projects, but hardly supported with current technology, and still a very difficult and ad-hoc process that depends on the skill and experience of individual modelers (Mclean, 2001; Robinson, 2004)
