![]() ![]() A bond-associative damage correspondence modeling approach is adopted to use classical failure criteria at the bond level, which readily enables the simulation of brittle and ductile fracture. 3D rate-form material models are employed to enable simulating a wide range of material behavior. Only the mid-surface velocity degrees of freedom are used in the governing thin-shell equations. A bond-stabilization technique is employed to naturally achieve stability of the discrete solution. The KL shell kinematics is utilized to develop a correspondence-based PD formulation. To remove the need for a predefined global parametric domain, Principal Component Analysis is employed in a meshfree setting to develop a local parameterization of the shell midsurface. We present a comprehensive rotation-free Kirchhoff–Love (KL) shell formulation for peridynamics (PD) that is capable of modeling large elasto-plastic deformations and fracture in thin-walled structures. ![]()
