Elastic properties are important in fundamental understanding of multiferroic materials. However, up to now, there is no work about anisotropy of elastic properties in orthorhombic Ca3Mn2O7. In this study, using coordinate transformation method, we investigated basic elastic parameters (elastic constants c0 i j) and engineering elastic parameters (Young’s modulus E0, Poisson’s ratio v0, and the rigidity modulus G0) of orthorhombic Ca3Mn2O7 along arbitrary orientations. The detailed anisotropic characteristics of these parameters were presented. The results reveal the orientation related elastic properties in mm2 point group orthorhombic Ca3Mn2O7.
