ABSTRACT = {A recently developed novel three-dimensional (3D) computational 
framework for the analysis of polycrystalline materials at the grain scale is 
described in this lecture. The framework is based on the employment of: <i>i</i>) 3D 
<i>Laguerre-Voronoi tessellations</i> for the representation of the micro-morphology 
of polycrystalline materials; <i>ii</i>) <i>boundary integral equations</i> for the 
representation of the mechanics of the individual grains; <i>iii</i>) suitable <i>cohesive 
traction-separation laws</i> for the representation of the multi-physics behavior of 
the interfaces (either inter-granular or trans-granular) within the aggregate, which 
are the seat of damage initiation and evolution processes, up to complete decohesion and failure. The lecture will describe the main features of the proposed 
framework, its main advantages, current issues and direction of potential further 
development. Several applications to the computational analysis of damage 
initiation and micro-cracking of common and piezoelectric aggregates under 
different loading conditions will be discussed. The framework could find 
profitable application in the multiscale analysis of polycrystalline components 
and in the design of micro-electromechanical devices (MEMS).},
