Molecular dynamics simulation of tensile tests at a curved binder-particle interface

Molecular Dynamics Simulations of tensile tests at a curved and flat polybutadiene + crystalline Aluminum interface under lateral confinement are performed. Results indicate comparably high stress in three stages from formation, enlargement and coalescence of polymer voids. This is attributed to the lateral confinement of the system. Values of the curved surfaces are roughly 20% higher as stress is localized at the tip of the curved surface. At higher strain, where the polymer forms a single strand above the Al crystal, values for both interface types coincide within measurement precision.
