A variational model based on isogeometric interpolation for the analysis of cracked bodies
TL;DR: In this paper, a variational model for the analysis of crack evolution is presented, which considers strong discontinuities that evolve according to the principles of cohesive fracture mechanics, and a method for tracking the discontinuity is also proposed, based on a local distortion of the parametrization of the geometry obtained determining the position of the control points of the isogeometric interpolation.
Journal ArticleDOI
A framework of elastic–plastic damaging model for concrete under multiaxial stress states
TL;DR: In this article, a constitutive model for concrete characterized by a combined plastic-hardening-damage-fracture dissipative criterion developed within the framework of the simple material model is presented.
Journal ArticleDOI
A new thermodynamically consistent continuum model for hardening plasticity coupled with damage
TL;DR: In this paper, a phenomenological model for hardening-softening elasto-plasticity coupled with damage is presented, where specific kinematic internal variables are used to describe the mechanical state of the system.
Journal ArticleDOI
A concrete homogenisation technique at meso-scale level accounting for damaging behaviour of cement paste and aggregates
TL;DR: In this article, a meso-scale model of concrete composite is proposed, which considers the composite as a multi-phase material and uses a random generation of phases distribution to predict the structural properties of concrete.
Journal ArticleDOI
A reconstructed local B̄ formulation for isogeometric Kirchhoff–Love shells
TL;DR: In this article, an efficient assumed strain formulation for avoiding the membrane locking of non polar shells is developed in the context of B-spline interpolation, where assumed membrane strains are introduced locally in each element with a local L 2 -projection, and then a spline reconstruction algorithm is employed for reconstructing the membrane strain at the global patch level.
