In this paper, the numerical solution of time-fractional convection diffusion equations (TF-
CDEs) is considered as a generalization of classical ones, nonexponential relaxation …

A non-local numerical model for large deformation analysis of functionally graded beam
(FGB) with variable cross-section is presented by using peridynamic differential operator …

In this paper, we present two non-local mechanics models of recycled coarse aggregate
(RCA) concrete based on peridynamics modeling and simulation, ie RCA model 1 and RCA …

The non-ordinary state-based peridynamic (NOSB PD) model has the capability of
incorporating existing constitutive relationships in the classical continuum mechanics. In the …

In this paper, the virtual crack closure technique (VCCT), commonly used in the numerical
finite element method (FEM), is for the first time reformulated in nonlocal peridynamic theory …

As a mathematical expression of the dynamic mechanical behavior, the constitutive model
plays an indispensable role in numerical simulations of ceramic materials. The current bond …

In this study, a peridynamic fiber-reinforced concrete model is developed based on the bond-
based peridynamic model with rotation effect (BBPDR). The fibers are modelled by a semi …

In this work, we present an innovative simulation method for quasi-static crack propagation
in mixed-mode, within a new framework of coupled peridynamics least square minimization …

The fracture process and breaking capability of ice cover impacted by high-speed projectiles
before underwater explosion is an urgent subject of scientific research in ice engineering …
