Abstract:
Plane shear defemation
is an important factor governing the deformation behavior of sheet
metal. In this paper, first, the characteristics of a newly-designed
testing device for simple sheer deformation in plane are described.
Second, according to the test, the stress-strain curves for three kinds
of aluminlum sheet metals (LY12M, LF21M, LC4M) are obtained and
discussed in connection with the planar anisotropy of material behavior
in the-plane simple shear and uniaxial tensile characteristics. Third,
Bauschinger effect in simple shear deformation is measured.
