In this paper, the mechanical behavior of bio-inspired nacre-like staggered composites is studied. The materials, combining stiff and soft constituents, exhibit superior properties. Here, attention focused on competing properties: penetration resistance flexibility composites. To end, a novel hybrid multiscale method developed, hierarchical approach with concurrent approach. allows to perform accurate parametric nonlinear analyses at low computational cost. influence microstructural...

Recent progresses in nanotechnology have clearly shown that the incorporation of nanomaterials within concrete elements leads to a sensible increase strength and toughness, especially if used combination with randomly distributed short fiber reinforcements, as for ultra high-performance fiber-reinforced (UHPFRC). Current damage models often are not able accurately predict development diffuse micro/macro-crack patterns which typical such structures. In this work, cohesive interface approach...

Abstract In this work, a refined interelement diffuse fracture theoretical model, based on cohesive finite element approach, is proposed for concrete and other quasibrittle materials. This model takes advantage of novel micromechanics‐based calibration technique reducing the artificial compliance associated with adopted intrinsic formulation. By means technique, required values elastic stiffness parameters to obtain nearly invisible interfaces are provided. Furthermore, mesh‐induced...

Abstract This work proposes a finite element (FE)‐based numerical model that uses the moving mesh technique for simulating fatigue crack propagation phenomena inside material components subjected to cyclic loads. Precisely, computational is adjusted during simulation according conditions dictated by criteria of fracture mechanics. Unlike standard FE procedures, which perform remeshing each increment length, proposed updates only when FEs are distorted excessively because nodes' motion, thus...

An accurate and fast failure simulation for masonry walls is still an active field of research, due to its fundamental role in predicting the overall response structures under seismic other extreme natural manoriginated events. Multiscale models have been successfully exploited achieving this task, being characterized by high computational efficiency, especially presence strong nonlinearities multiple microcrack initiation propagation. In paper, a novel multiscale/multidomain approach...

Abstract This work presents the numerical application of diffuse cohesive interface model introduced in Part I paper to failure analysis plain and reinforced concrete structures, subjected complex loading conditions, inducing mixed‐mode fracture initiation propagation. With aim capturing interaction between steel reinforcements, adopted is incorporated a novel, more general framework for nonlinear structures. Such includes newly proposed embedded truss reinforcing bars, allowing them be...
