Bond-based peridynamics for simulating fracture in wood
Please login to view abstract download link
Peridynamics (PD) is a non-local mesh-free continuum mechanics theory capable of modelling the formation and evolution of discontinuities in elastic materials [1]. PD therefore seems a reasonable candidate for simulating fracture in wood, which is quasi-brittle in nature. In this study, the simplest variant of PD, namely bond-based PD (BB-PD), is used to simulate fracture in wood compact tension (CT) specimens and plywood panels penetrated by a conical impactor. The talk summarizes the strengths and limitations of peridynamics and bond-based peridynamics in particular. It also discusses the results of a sensitivity study focusing on failure stretch ratio, bond length and horizon size.
