A technique for share strain test of sheet metal has been developed allowingthe equivalent stress-equivalent strain curve determination. Because an previous versionof testing device and specimen shows strain concentration at the corner of tested area,was performed a FEM optimization of the specimens shape and dimensions. Changingthe length of tested area and the testing device design, allows more accurate results ofsharing test. The method of strain share test is quite reliable and can be used in the studyof forming behaviour of sheet metals, and compared with the tensile and other testingmethods.
