Abstract

The main objective of this study is experimental tests and numerical modeling of forming and annealing processes of CuZn30 brass cylinder. In order to determine the grain size and shape, before and after heat treatment processes, metallography is conducted on the surface of the cylinder and during that, the impact of Work hardening to change of the material yield strength, specified. Numerical Modelling of forming stages, have been conducted with the finite element method. The purpose of numerical simulation is to determine the effects of parameters such as friction coefficient, Work hardening and anisotropic properties of primary sheet metal on limiting drawing ratio, force exerted on the drawing punch and final geometry. The results show that the friction coefficient have influence on the effective strain distribution, while Work hardening exponent have little effect. Force exerted on the drawing punch is affected by changing the Work hardening exponent. Some defects are caused in experimental samples, was analyzed by finite element method and the causes of appEaring defects identified and were used in experimental tests. On the end, geometries obtained using simulations have been compared and verified with experimental tests. The output results show good agreement with experimental tests
