ABSTRACT Stress-strain diagram is a very useful diagram for finding the physical properties of metals. Especially by the tensile test in Universal Testing Machine (UTM), we can find the load-displacement diagram and there by stress-strain diagram. From this diagram by suitable correction, also we can get the true stress-strain diagram. But, as we know that the Poisson’s ratio (μ) for metal is not a constant terms above elastic limit because above the elastic limit the metal expansion is not remain uniform. So, in our current research by finding suitable correction method of finding the true μ value and considering this we can find the corrected stress- strain diagram. For this we made experiments on different metals, namely aluminum, copper & brass and there by finding their respective corrected stress-strain diagram we tried to establish this methodology. |
