title = "Mullins' effect in polymer/clay nanocomposites: Observations and constitutive modeling",
abstract = "Experimental data are reported on polypropylene/clay nanocomposites in uniaxial cyclic tensile tests at room temperature (oscillations between maximum strains and the zero minimum stress with maximum strains increasing monotonically with number of cycles). Observations reveal fading of memory of deformation history: when two samples are subjected to loading programs that differ along the first n - 1 cycles and coincide afterwards, their stress-strain diagrams coincide starting from the nth cycle. Constitutive equations are developed in cyclic viscoelasticity and viscoplasticity of nanocomposites, and adjustable parameters in the stress-strain relations are found by fitting the experimental data. Ability of the model to predict the fading memory phenomenon is confirmed by numerical simulation.",
