This study presents a coupled thermo-fluid-mechanical peridynamic model to predict composite responses under fire scenarios. Three-layer laminated is modelled by using ordinary state-based thermo-mechanical peridynamics. Both the mechanical deformation and heat conduction are simulated considering thermal degradation properties of composites. The as heat-conducting fluid thermo-fluid based on d...

Peridynamics (PD) is a nonlocal continuum theory based on integro-differential equations without spatial derivatives. The elongation fracture criterion is implicitly incorporated in the PD theory, and fracture is a natural outcome of the simulation. On the other hand, a new fracture criterion based on the crack opening displacement combined with peridynamic (PD-COD) is proposed. When the relati...

The cubic silicon carbide (3C-SiC) has broad application prospects due to its excellent properties. modeling of damage in 3C-SiC contact loads is important yet challenging. In this paper, simulations based on peridynamics theory are proposed model indentation and scratching. indentation, the pop-in phenomenon load-depth curve initiation propagation cracks observed. During scratching, specific c...

A classical continuum mechanics model no longer fulfills its basic assumptions, when the deformations are not smooth or discontinuous. Peridynamics (PD) as an integral formulation could better overcome these issues. Therefore, it is suited to solve fracture problems such crack initiation, growth and formation of patterns. In PD magnitudes internal forces at a material point depend on collective...

Abstract In this study, a new peridynamic Mindlin plate formulation is introduced by utilising Euler-Lagrange equations. The classical strain energy density of material point converted to its corresponding form using Taylor’s expansions. suitable for thick plates considering the transverse shear deformation. Material constants do not have any limitation in current formulation. Different types b...

In this work we aim to develop a unified mathematical framework and reliable computational approach model the brittle fracture in heterogeneous materials with variability material microstructures, provide statistic metrics for quantities of interest, such as toughness. To depict responses naturally describe nucleation growth fractures, consider peridynamics model. particular, stochastic state-b...
