Local-nonlocal coupling approaches provide a means to combine the computational efficiency of local models and accuracy nonlocal models. This paper studies continuous discrete formulations three existing for classical linear elasticity bond-based peridynamic models, namely 1) method that enforces matching displacements in an overlap region, 2) variant constraint on stresses instead, 3) consider...

This study presents a novel peridynamic model for geometrically nonlinear analysis of three-dimensional beam structures. The formulations strain energy densities is obtained by using Total Lagrange formulation. structures are based on the principle virtual displacements. capability proposed demonstrated considering large deformations straight beams and curved subjected to different loading cond...
