Il lavoro si inquadra nell'ambito delle ricerche che considerano la muratura come un mezzo continuo le cui equazioni costitutive tengono in conto la struttura ordinata del materiale. Viene presentata una generalizzazione del modello cinematico proposto in un precedente lavoro limitato alla descrizione dei meccanismi di deformazione anelastica...

By considering a tensorial description of the damage and of the unilateral and frictional effects on the displacement jump across the crack faces, an anisotropic constitutive model based on the assumption of linear elastic matrix weakened by microcraks is derived. Damage and sliding evolutions are obtained on the basis of proper limit...

An anisotropic constitutive model based on the assumption of linear elastic matrix weakened by microcraks is derived by assuming a tensorial description of the damage and of the unilateral andfrictional effects on the displacement jump across the crack faces. Damage and sliding evolutions are obtained by defining proper limit conditions and...

Damage in quasi-brittle materials takes place progressively with a nonlinear response and greater strength under compression than tension. This damage behavior may be interpreted as an effect of micro-crack nucleation and growth inside an elastic matrix. Because these materials sustain mainly compressive stresses, the resulting stress...
