Abstract: This paper simulates fracture in notched mortar beams under three-point bending using an extended finite-element method (XFEM) and peridynamics. A three-phase microstructure (i.e., cement paste, aggregates, and ...

Abstract: Generalized constitutive models, which can be used in explicit finite-element analysis, are being developed to accurately model composite systems under impact conditions. These models require extensive characterization of ...

Abstract: The need for accurate material models to simulate the deformation, damage, and failure of polymer matrix composites under impact conditions is becoming critical as these materials are gaining increased usage in the aerospace ...
