ZOR MODEL

Zor Model: This is a new equivalent volume model developed for layered composite structures. Its most important and distinctive feature, compared to other models, is that it incorporates Poisson interactions between the layers at the system level. Important information about the Zor Model is presented below. Further information may be added to this page over time.
