A failure criterion for genuinely orthotropic materials and integration of a series of criteria for materials of different degrees of anisotropy (2024)
Journal Article

Existing failure criteria for orthotropic materials are subject to an underlying assumption which cause contradictions when applied to genuinely orthotropic materials that are significantly anisotropic in elasticity as well as in strengths. For such... Read More about A failure criterion for genuinely orthotropic materials and integration of a series of criteria for materials of different degrees of anisotropy.
