Özet
In this article, elastic modulus and yield strength of models with specific geometry are evaluated. Experimental and theoretical studies were carried out. Produced models were subjected to compression test under one press and analysis (FEA) in ANSYS program. The results were used to determine the most suitable porosity in terms of strength, ductility, and weight loss. The results were used to assess the percentage of proper porosity that protects the force, ductility and weight reduction. Durability, elastic and plastic module yield decreased with increasing porosity. The most important change occurred in the elastic modulus.
