Methods for measuring friction-independent flow stress curve to large strains using hyperbolic shaped compression specimen

The accurate measurement of flow stress curve to large strains using cylindrical compression specimen is always a great challenge due to the influence of friction. Recently, the present authors designed a hyperbolic shaped compression (HSC) specimen which can yield an average true stress- strain cur...
