It is possible erihsen delay the crack detection using a potentiometer. Often this facility is necessary for testing thicken sheet metal panels in order to achieve a uniquely defined crack in conformity with the standards. The entire test procedure runs automatically, including crack detection. PDF | Modified Erichsen cupping test is on of the currently used formability test, which evaluate the ability of sheet metal to be formed into useful.Īfter pressing the “Start” push button the sheet holder force of 10kN as well as the drawing speed – both conforming to the standards – are adjusted automatically and the test procedure is initiated.Īs the testing machine is equipped with the function “automatic stop at specimen failure” the cupping procedure is automatically interrupted when a erichsdn appears so that an objective test result will always be achieved. Abstract-Modified Erichsen cupping test is on of the currently used formability test, which evaluate the ability of sheet metal to be formed into useful components.
