Ⅰ. CONSTITUTIVE RELATIONConsider the Ramberg-Osgood materials. Their shear strain-shear stress relation takes the formγ= τ+ ατ~n. (1.1)The nondimension stress is used throughout this note, which is nondimensionalized by shear yield stress. Meanwhile the nondimension strain is employed, which is nondimensionalized by the shear yield strain.
