Abstract
This work describes two newly developed computational tools that greatly improve the efficiency and the applicability of peridynamics-based software to computational mechanics.
The first contribution is concerned with a new, flexible and accurate way to couple peridynamic grids to FEM meshes. The coupling produces a new computational method that applies FEM or PD discretisations where required and couples them in a way that keeps the advantages of both approaches and avoids their pitfalls.
The second contribution is about a simple and accurate implicit solution of static problems in which the usual prototype microelastic brittle material (elasto-brittle) model is adopted.
Finally a computational example is presented to show the potentialities of the new computational techniques.
