Annotation	The paper presents a study of the behavior of a numerical model of peridynamics for various influence functions using the example of two-dimensional elasticity problems with an analytical solution and fracture problems. The influence function is used to define the model in integral relations and describes the behavior of non-local particle interactions. It is shown that the best convergence of the implemented model is achieved by using the cubic spline type influence function.
Keywords	peridynamics, continuum mechanics, interaction horizon, strain gradient tensor, influence function.
