A finite deformation phase-field fracture model for the thermo-viscoelastic analysis of polymer nanocomposites

The prediction of failure processes in polymer nanocomposites requires accurately capturing different factors such as damage mechanisms, and temperature- and rate-dependent material characteristics. This work presents the development of a finite deformation phase-field fracture model to analyze the thermo-viscoelastic behavior of boehmite nanoparticle/epoxy nanocomposites. To characterize the rate-dependent fracture evolution, the free energy is...
