• Yield criterion of anisotropic materials is developed under the maximum shearing stress hypothesis when the elements of materials are acted upon by three normal stresses in the direction of principal axes of anisotropy and a shearing stress around one of them. It is found for isotropic materials that the yield surface can be represented by two elliptical cone surfaces and a cylindroid one in the stress co-ordinate which is composed of the π-plane and its normal as a shearing stress. Under the assumption that these surfaces are independently distorted, translated and rotated, the numarical yield surface of anisotropic materials is found to be in good agreement with the experimental results of plates in any direction other than the direction of the degrees of angle, 60° to 70° form initial path of tensile prestrain.
