Abstract

A criterion is presented for the prediction of failure of anisotropic materials under combined loading. Although tensorial in nature, the criterion is represented in a matrix form for ease of visualization. The approach is developed in detail for orthotropic materials under plane stress, but is applicable to general three-dimensional anisotropic materials. Two concepts are introduced: the interaction factor, which is a measure of strength anisotropy; and the principal strength axes, which are related to the directionality of the material strength properties. The criterion provides description of strength phenomena peculiar to fiber composite materials, but it is also applicable to homogeneous anisotropic metals. © 1972 American Institute of Aeronautics and Astronautics, Inc.
