A Critical Evaluation of Computational Fracture Using a Smeared Crack Approach in MPM
An evaluation of the smeared crack representation of material failure using the material-point method (MPM) as a feasible computational failure approach is performed. The spatial descretization in MPM is defined by a grid of cells that represent space and a set of points that represent the …

Modelling of transport processes involved in service life prediction of concrete: important principles
… the stress-deformation state using the so-called smeared crack approach.

A Mesh Objective Algorithm for Modeling Mode-I Cracks Using a Standard Finite Element Formulation
… mesh objective algorithm for modeling mode-I cracks is developed and implemented within a standard finite element formulation. The algorithm applies the crack opening displacements across the standard nodal degrees of freedom that is consistent with formalism of the conventional smeared crack …

Punching shear capacity of flat slab-column junctions (a study by 3-D non-linear finite element analysis)
… to describe the behaviour of concrete before cracking or crushing. After cracking, a yield criteria for 2-D model similar to Kupfer-Hilsdorf was used and concrete was assumed to be anisotropic. No softening in compression is assumed. Smeared crack approach with simple tension stiffening and …

Delamination in reinforced concrete retrofitted with fiber reinforced plastics
… causes, specifically in the presence of existing cracks in the retrofitted concrete system. First, delamination processes in FRP retrofitted concrete systems are studied through combined experimental and analytical procedures. The delamination process is observed to initiate in the concrete …

The mathematical modelling of concrete constitutive relationships
… materials in addition to factors such as cracking, crushing, aggregate interlock, creep, shrinkage, bond slip and rate of loading. Analytical methods have been improved in the past two decades as a result of the availibility of more powerful computers. It is, therefore, feasible to model …

Modellazione numerica della nascita e dello sviluppo di interfacce mediante il metodo delle discontinuità forti
… approccio al continuo con fratture distribuite (smeared crack approach). Quest'ultimo, sebbene vantaggioso dal punto di vista dell'implementazione numerica, presenta problematiche legate alla non oggettività della risposta al variare della discretizzazione adottata (mesh-dependency) a causa del …

Nonlinear finite element analysis of reinforced concrete structures subjected to blast loading
… principle of virtual work in total Lagrangian approach. The finite element discretization of the equations of motion in space is adopted in accordance with isoparametric formulations. The steel reinforcement is modelled by bar or membrane elements embedded within the basic 8-node isoparametric …
