DOI: 10.1007/s10704-016-0167-x
Abstract: An energy minimization approach to initially rigid cohesive fracture is proposed, whose key feature is a term for the energy stored in the interfaces that is nondifferentiable at the origin. A consequence of this formulation… read more here.

DOI: 10.1016/j.finel.2021.103527
Abstract: Abstract We propose a geometrically nonlinear extended isogeometric analysis approach for cohesive fracture. A shifting technique is used to enforce compatibility in the direction perpendicular to the crack path, while a blending technique has been… read more here.

DOI: 10.1142/s0218202518500379
Abstract: In this paper we prove the existence of quasistatic evolutions for a cohesive fracture on a prescribed crack surface, in small-strain antiplane elasticity. The main feature of the model is that the density of the… read more here.

DOI: 10.1177/1081286519870222
Abstract: We derive a homogenized mechanical model of a masonry-type structure constituted by a periodic assemblage of blocks with interposed mortar joints. The energy functionals in the model under investigation consist of (i) a linear elastic… read more here.
