  1. Coefficient of variation is in the parentheses, unit: %. Subscript L represents the parallel grain direction, R represents the radial direction, and T represents the tangential direction. The elastic modulus E, Poisson’s ratio v, shear modulus G, tensile strength ft, compressive yield strength fcy, shear strength fLR, fLT and fRT can be obtained by strain gauges adhered to the specimens
