Abstract

One of the important input factors used in FEM analysis, or analytical calculations, is the material model data. Over the years, various models of the material flow curves have been proposed. Those models, ranging from ideal plastic material data modelling (simple, but useful for hot plastic forming) to elastic-ideal plastic models, to elastic-strain hardening plastic models, and to definition of plethora of data points for piecewise-linear methods, are commonly used in research papers to describe material behaviour till today. The mathematical models made by approximation of measured results from the tensile tests, have been proven to be the most elegant ones. In this paper, a general data obtained from series of uniaxial tensile tests of HC180Y interstitial free steel metal sheets is given. Coefficients of determination R2 of the mathematical models are also given. This research has been carried as preparation work for subsequent research related to modelling of joining process by mechanical clinching of dissimilar sheet metal plates.
