Uncertainty quantification of the fracture properties of polymeric nanocomposites based on phase field modeling

A sensitivity analysis (SA) has been conducted to examine the influence of uncertain input parameters on the fracture toughness of polymeric clay nanocomposites (PNCs). In order to predict the macroscopic properties of the composite, a phase-field approach has been employed considering six input parameters. For computationally efficiency, the SA is performed based on a surrogate model. Screening methods of the Standardized Regression...
