The effective elastic constants of textured polycrystalline materials are calculated in two approximations on the basis of a minimum energy assumption which is more realistic than the V OIGT and R EUSS assumptions. The formulae are specified for the case of cubic crystal symmetry and orthorhombic specimen symmetry (sheet symmetry). Numerical values calculated for a copper and a steel sheet are compared with the corresponding experimental values.
