In the present paper the corrosion properties of structured sheet metals were investigated. The aim of this work is to determinate the influence of the structuring process on the corrosion resistance of sheet metals. For this purpose, these sheets were examined by accelerated tests in corrosion chamber. The investigation was carried out using salt spray test. The experiment was conducted for th...

In this research, Forming Limit Diagrams for supertension sheet metals which are using in automobile industry have been obtained. The exerted strains to sheet metals have been measured with four different methods and the errors of each method have also been represented. These methods have been compared with together and the most efficient and economic way of extracting of the exerted strains to...

The r-value of a sheet metal is a measure of plastic anisotropy frequently used for prediction of performance in deep-drawing. It has also gured prominently in the literature for validation of theories where the predicted angular dependence of r is compared with the measured dependence. As plastic anisotropy in sheet metals is caused mainly by the preferred orientations of grains within the pol...

Fukui’s conical cup test is the one of the formability characteristics evaluation for various sheet metals. The formability characteristics such as diametrical ratio, maximum drawing load, depth of cup up to fracture are to be evaluated. This test is related to drawing test. This test can be performed by using parameters such as friction, process parameters and without blank holder. In fukui’s ...
