PROCESS TESTING SHEET METAL FOR TWO-AXES TENSION Russian patent published in 1999 - IPC

Abstract RU 2125255 C1

FIELD: plastic metal working. SUBSTANCE: process consists in placement of sample of tested material in die, in pressing of it against die, in heating and loading of it with deformation effort through working medium Sample is heated directly in die by means of electric contact. Matrix of die is made from nonconductive material. Loose heat- resistant, nonconductive material is used in the capacity of working medium. EFFECT: reduced labor input, simplified testing and expanded temperature range. 1 dwg
