More anisotropic materials than ever before are being used as technological and material developments continue to advance the field of solid mechanics; everything from Magnesium sheet and NiTi tubes to additively manufactured Inconel and fiber reinforced composites possess anisotropy. As recently brought to light in ‘New Perspectives on Elastic Limit Hypersurfaces: The Need for Six Dimensions in Modeling Anisotropic Materials,’ the elastic limit of a material describes a bounding hypersurface in six dimensions, and when considering anisotropic materials all six dimensions are necessary. Classical approaches to calibrating yield criteria have hinged on graphical techniques which were limited to at most a three-dimensional platform. This presentation explores how to extend these graphical techniques to appropriately address all six dimensions, introduces equation-based calibration approaches, and presents a collection of analytic and experimental case studies for calibrating a complete six-dimensional yield hypersurface.
