Understanding masonry behaviour through DEM: influence of mortar quality and pre-existing damage under compression

Constitutive modeling of concrete under tensile loading: damage evolution from 3D microcracks

Detailed micro-modelling of unreinforced masonry walls: a parametric in-plane cyclic study

Unreinforced masonry walls (UMWs) exhibit insufficient seismic capacity owing to their low tensile strength, rapid stiffness degradation, and brittle failure under cyclic in-plane loading. This study proposed a detailed micro-modelling approach to simulate the in-plane behaviour of UMWs. The finite element model was in...

Different modelling techniques on compressive behaviour of masonry columns

Many existing masonry columns have experienced significant material deterioration, requiring reliable methods for structural assessment and rehabilitation planning. This study evaluates the compressive behaviour of three-dimensional masonry columns under axial compression using two finite element modelling strategies:...

Numerical modeling of concrete fracture and size effect using position-based high aspect ratio solid elements

The size effect, defined as the reduction in nominal structural strength with increasing size, is a critical phenomenon in concrete and other quasi-brittle materials, governed by fracture processes such as crack initiation, propagation, and localization within the fracture process zone (FPZ). As the structural size inc...

Dynamic fracture modeling in ductile materials using phase field approach

Understanding dynamic fracture in both brittle and ductile materials has attracted considerable attention from engineers and researchers due to its practical importance. In ductile materials, crack initiation and growth are strongly influenced by plastic deformation and the associated microstructural damage, which grad...

Damage Plasticity Modeling of a Concrete Block Masonry Material

Masonry walls constructed of brick or block units have tended to suffer more serious damage when subjected to loads of both static and cyclic (such as an earthquake) nature as compared to other concrete or steel structures. Hence, the static and cyclic loading behavior of these masonry building units should be carefull...
