The objective of this report is to introduce, implement and assess a two-scale FE technique for the mechanical study of heterogeneous quasi-brittle materials. Although the field of multi-scale analysis of structures is being intensively studied nowadays, some important issues regarding its applicability, convenience and performance remain unclear for certain engineering cases.
