A new material model for the dynamic fracture analysis of anisotropic materials has been proposed within the framework of the bond-based peridynamic theory. This model enables predicting complex fracture phenomena such as spontaneous crack nucleation and crack branching, curving and arrest, a capability...
The so-called fragmentation in which multiple cracks appear and extend simultaneously and break into multiple fragments: the crack-free bodies with mesoscopic damage, through the nucleation, growth, and coalescence of the multisource mesoscopic damage, will eventually form multiple macroscopic cracks and...
Abstract A nonlocal model for dynamic brittle damage is introduced consisting of two phases, one elastic and the other inelastic. Evolution from the elastic to the inelastic phase depends on material strength. Existence and uniqueness of the displacement-failure set pair follow from an initial value...
Peridynamic (PD) models of bodies without pre-cracks, based on a single fracture parameter (associated with the critical fracture energy), produce different strengths when different horizon sizes are used to simulate crack nucleation under quasi-static conditions. To maintain the same strength and ...
Subsequently, numerical simulations are used demonstrate the capabilities of the peridynamic model for capturing mechanics of corroding solid. The framework is able to capture corrosion pitting, nucleation, crack path propagation under synergistic influence of corrosion and mechanical loading, without the ...
Corrosion fatigue crack nucleation is a local damage evolution process and the stress intensity factor criterion is one of the critical conditions to discern whether a crack sprouts at the corrosion pit. This paper establishes a corrosion pit-crack model based on the overall finite element model of...
