Some characteristics of orthotropic materials revealed by special mechanical testing and their FLD’s

Usually, in order to determine the mechanical characteristic of metallic material is used the tensile test. But, for orthotropic sheet metal testing the tensile test become not representative and is proposed the utilization of planar sharing, planar stretching and compression tests. Those testing methods are ease to implement on conventional testing machines and the obtained results may be used in the sheet metal forming analysis and in the understanding of mechanical behaviour of orthotropic materials.
