Seismic Assessment of a Medieval Masonry Tower in Northern Italy by Limit, Nonlinear Static, and Full Dynamic Analyses
A comparative numerical study on a 12th-century masonry tower located in northern Italy is described. To assess the safety of the tower under seismic loads, different numerical analyses have been
Simulation of finite-width process zone in concrete-like materials by means of a regularized extended finite element model
Experimental tests carried out on concrete specimens show that a fracture process zone with finite width develops in front of the crack tip. Currently, the only way of modelling a finite-width
A regularized XFEM model for the transition from continuous to discontinuous displacements
This work focuses on the modelling through the extended finite element method of structural problems characterized by discontinuous displacement. As a model problem, an elastic isotropic domain
