S. Marfia et alii, Frattura ed Integrità Strutturale, 18 (2011) 23-33; DOI: 10.3221/IGF-ESIS.18.03 31 Figure 4 : Numerical results obtained adopting the Model 2. a) Mechanical response of whole structure; b) Mechanical behavior of interface; c) Body tensile response. Maximum decohesion force The computations are performed considering the scheme and the geometry illustrated in Fig. 5. The FRP laminate (body 2  ) is bonded to a masonry support (body 1  ) made of two clay bricks separated by an unitary layer of mortar. The FRP laminate is subjected to tensile loading.
