Abstract
Strength of unidirectional composite materials for some combinations of state of stress cannot be successsfully
predicted even with modern failure criteria. In case of the combination of compression in the transverse direction
and tension in the fiber direction, the criterion LaRC04 was adjusted in previous work. The predicted strengths
in this case reach significantly larger values compared to the ultimate strengths of the material in the respective
directions. The adjusted criterion is able to predict the failure of unidirectional composite in case of the mentioned
combination of loading. The validation of the adjusted criterion is carried out by means of the comparison of
experimental results and numerical analysis performed in finite element system MSC.Marc.
