Witrynato distinguish between initial and actual states in the nonlinear theory does not allow one to be content with considering a single strain measure. For this reason, it is expedient to introduce more rigorous tensors to describe the stress-strain state. These are considered in Section 1.3 for which the study of Sections 2.3-2.5 should precede.

WitrynaNumerical simulations are presented of the cracking that develops for varying geometrical configurations of the glass plates under in-plane loads, using a plane stress ordinary state-based peridynamics formulation. The fracture patterns and failure loads predicted by the models agree reasonably well with corresponding experimental observations. Witryna30 lip 2024 · In the current research, we propose a novel non-ordinary state-based peridynamics (PD) fatigue model for multiple cracks’ initiation and growth under tension–tension fatigue load. In each loading cycle, the fatigue loading is redistributed throughout the peridynamic solid body, leading to progressive fatigue …

WitrynaAbstract Ordinary state-based peridynamics (OSBPD) is a well-established peridynamic (PD) model, but its applications are restricted in brittle fracture because the failure models proposed in OSBPD are mainly to describe brittle fracture rather than quasi-brittle fracture. This work attempts to propose a damage model to overcome …
