Modelli 2D con microstruttura per pannelli di muratura in 3D

Abstract

In [Masiani et al.,1995] si `e proposto un modello di continuo con microstruttura per l’analisi di sistemi costituiti da blocchi rigidi e interfacce elastiche in 2D. Per tenere in conto i moti fuori dal piano (vedi Figura 1) gli autori, [Cecchi e Rizzi, 2003] hanno sviluppato una procedura di identificazione tra un modello con blocchi rigidi e interfacce elastiche inizialmente piano ma immerso in uno spazio 3D, e una piastra di Mindlin Reissner. In questo lavoro si propone di identificare lo stesso sistema di blocchi con un modello di continuo bidimensionale ad ogni punto del quale `e associata una microstruttura rigida 3D. Rispetto alla piastra, l’atto di moto `e piu` ricco perch ́e la velocit`a angolare della microstruttura `e descritta da un tensore antisimmetrico completo, mentre le azioni di contatto sono rappresentate da due tensori che in generale non hanno nessuna propriet`a di simmetria e che descrivono la forza e la coppia di contatto, rispettivamente.
