NUMERICAL SIMULATION ON THE MECHANICAL BEHAVIOR OF WATER-CONTAINED PEM

摘要：

In this paper,at first,MD simulation is performed to clarify the effect of water content on the distribution of density of molecular chains of PEM under uniaxial tension.It is found that the lower water content the more remarkable change of the density of molecular chains of PEM,which may lead to a high possibility of the nonaffine movement of the physically entangled points in the molecular network.Continuously,a computational model,in which the development of the deformation resistance is assumed to be a function of the number of the physically entangled points,is employed to discuss the effect of the water content on the mechanical behavior of PEM under various loading condition.
