In our previous paper, the dynamical mechanical model under the uni-axial load has been established and the theoretical analysis showed good agreements with the experimental results. This paper presents the multi-axial model which is developed to analyze the behavior of composite materials. As a result of the study Poisson's ratio was found to be the stress dependent and a new concept regarding composite materials was suggested. Furthermore, the behavior of fracture mechanism for composite materials became clear using the mechanical model presented here.
