Setup.The tensile test is one of the most important testing methods for characterizing or obtaining material parameters.In the tensile test,for example,it is determined which load a material can withstand until it begins to deform plastically (yield strength) or under which maximum load the material breaks (tensile strength).The tensile test can also be used to determine the elongation at Tensile reduction in metal forming - TheArtofPressBrakeWhat is Tensile reduction in metal forming when bending sheet metal on a press brake? The answer is Tensile reduction in metal forming is no more than aTensile Testing and Hardness Testing of Various MetalsFeb 10,2016 tensile reduction percentage theartofpressbrake#0183;percentage (42%) and a relatively low yield strength (31.84 ksi).These properties make it easy to plastically deform and form into a shape.For similar reasons,the Cast Iron sample would be the most difficult material to plastically deform and form into a shape.

Tensile testing of metallic materials is specified according to European EN 10002 standard.In this article the terms,definitions and designation for tensile test made at ambient temperature is described.The test involves straining a test piece in tension,generally to fracture,Tensile Reduction Percentage TheartofpressbrakeJun 25,2015 tensile reduction percentage theartofpressbrake#0183;Tue,30 Jun 2015 16:35:27 GMT.I believe you are referring to the article I wrote sometime back The Fundamentals of heavy bending The Tensile Reduction Value used there was just another term to what I refer to as the 20%.TENSION TEST 1.OBJECT 2.INTRODUCTION 3.THEORY3 True stress is the stress determined by the instantaneous load acting on the instantaneous cross- sectional area (Fig.3).T = P/A i True strain is the rate of instantaneous increase in the instantaneous gauge length (Fig.3).T = ln (l i /l o) Figure 3.True Stress
