The effective properties of composite materials have been predicted by various micromechanical schemes. For composite materials of constituents which are described by the classical governing equations of the local form, the conventional micromechanical schemes usually give effective properties of the local form. However, it is recognized that under general loading conditions, spatiotemporal nonlocal constitutive equations may better depict the macroscopic behavior of these materials. In this pap...

Abstract Non-locality in elasticity of continua with microstructures has been described via integral formulations or by high-order gradient theories with respect to spatial variables. Although various non-local constitutive relations have been proposed, the origins of spatial and temporal non-localities and their physical mechanisms are still elusive. In this work, we develop an explicit spatiotemporal non-local dynamic constitutive formulation for composites composed of conventional local elast...

The famous Wieghardt, Griffith and Irwin criteria predict the onset of fracture in linear elastic materials. They have to be supplemented by appropriate criteria for predicting the path that the fracture will follow until the failure of the structure. These require the knowledge of the stress and displacement fields at the front of propagating fracture which depend on the actual loading on the structure and its boundary conditions. In this paper we shall review these fields in brittle and quasi-...

Abstract This paper critically examines the performance of reinforced concrete (RC) beams retrofitted with a thin strip of ultra-high performance fibre-reinforced concrete (UHPFRC) under cyclic loading. RC beams were preloaded under static loading approximately to 70%, 80% and 90% of maximum load of control beams and then tested under fatigue loading with a stress ratio of 0.1 and frequency 2 Hz after retrofitting with a UHPFRC thin strip of 10 mm thickness. It has been found that the damaged RC...

The aim of this paper is to describe the performance of reinforced concrete (RC) beams retrofitted with a self-compacting ultra-high-performance fibre-reinforced concrete (UHPFRC) under three-point bend cyclic loading. It is found that retrofitting the RC beams with a thin UHPFRC strip on the tension face increases their endurance limit under a non-zero mean stress cyclic loading from approximately 40% to approximately 60% of their static three-point flexural strength. Moreover, the retrofitted ...

Abstract The performance of popular techniques of rehabilitation and strengthening of concrete elements using externally bonded steel plates and fiber-reinforced plastic (FRP) laminates has been extensively investigated and several de-lamination failures have been reported primarily due to the mismatch of their tensile strength and stiffness with that of the concrete structure. To overcome some of these drawbacks, this paper critically examines the performance of Reinforced Concrete (RC) beams r...

espanolEn este articulo se analiza la utilizacion de un hormigon fabricado mediante cemento de endurecimiento ultra-rapido para la reparacion urgente en espacios confinados, donde los elementos reparados son sometidos a cargas dinamicas poco tiempo despues de su reparacion. La investigacion se centra principalmente en el estudio del desarrollo de la resistencia del material a edades tempranas, asi como de la integridad estructural del elemento reparado. El trabajo se ha dividido en 2 partes. En ...

Due to the demand for highly durable concrete structures, Self-Compacting Concrete (SCC) with its unique characteristics (flow-ability, passing ability and stability) has been developed, and is increasingly replacing Vibrated Concrete (VC) in various structural applications. SCC, which is characterised in its fresh state by high flow-ability and rheological stability, has excellent applicability for structural elements with complicated shapes and congested reinforcement. An incompressible mesh-l...

Abstract The flow of self-compacting concrete (SCC) mixes through a V-funnel is simulated from the moment the gate is opened until the time when the light was first seen in the bottom opening through observation from the top (discharge time, t v-funnel ). For this simulation, the three-dimensional mesh-less smooth particle hydrodynamics (SPH) computational approach is chosen in which the SCC mix is treated as a non-Newtonian Bingham-type fluid. The numerical simulation results for the discharge ...
