The Refined Zigzag Theory (RZT) for homogeneous, laminated composite and sandwich plates is developed from a multi-scale formalism starting with the in-plane displacement field expressed as a superposition of coarse and fine contributions. The coarse displacement field is that of

This book introduces the peridynamic (PD) differential operator, which enables the nonlocal form of local differentiation.  PD is a bridge between differentiation and integration.  It provides the computational solution of complex field equations and evaluation of derivatives of smooth or
