✦ Synopsis

The Yeh~tratton criterion (Y-S criterion) is a failure criterion developed from a macromechanics point of view. It requires three yielding strengths and other easily obtainable data to predict failure of materials. A failure criterion with the micromechanics point of view developed by Zhang, Wang, and Zhang was compared with the Y-S criterion and their results are examined along with experimental data.

In the unidirectional fiber reinforced composites, the experimental data favor the Y-S criterion strength predictions and the micromechanics failure theory offers higher critical values than the Y-S criterion. In the angle crack problems, the strengths are also predicted closer to experimental data by the Y-S criterion.
