Ordinary state based peridynamics

Witryna1 sty 2024 · This work presents an extended ordinary state-based peridynamics (XOSBPD) model for the non-spherical horizons. Based on the OSBPD, we derive the XOSBPD by introducing the Lagrange multipliers to guarantee the non-local dilatation … WitrynaA non-ordinary state-based peridynamics framework for anisotropic materials.
