Strength of a unidirectional material as well as a layered composite made of variously focused unidirectional layers can be investigated by two main approaches: phenomenologically and micromechanically. In natural sciences, phenomenological theories (in contrast to microscopic or structural, for example) are those that describe only phenomena and their consequences without explaining their causes. In this, the traditional phenomenological approach applies local stress or average stress failure criteria based on different approximations of experimental strength data. Finally, the transformations of failure criteria between inclined coordinate systems are presented.
