In this context, various techniques have been developed in the recent years to analyze the crack pattern and to detect fracture failure in advance. This paper presents the investigation of discrete crack propagation and the shear bearing behaviour of a concrete beam without transverse reinforcement ...
Adaptive control of multiple acoustic modes in cavities An experimental study is described in which a two-dimensional free turbulent shear layer at Mach 2. 92 and a high Reynolds number is reattached to an inclined surface. The test geometry is designed to create an undisturbed free shear lay....
A mechanical model for waves impinging different configurations of multiple shear bands already formed in a ductile material, allows to analyze the ways in which dynamic interactions promote failure. It is shown that the presence of more than one shear band may lead to resonance and correspondent ...
In recent earthquakes, a large number of reinforced concrete (RC) bridges were severely damaged due to mixed flexure-shearfailure modes of the bridge piers... Zhiguo,Sun,Bingjun,... - 《Earthquake Engineering & Engineering Vibration》 被引量: 31发表: 2008年 Seismic response analysis of road ...
When timber joint is loaded in tension perpendicular to grain, its failure may result either in yielding of the dowels, crushing of the wood under the dowels or splitting of the timber member. The first two failure modes are considered as a ductile failure, while splitting or fracture of ...
When you have more than three joint orientations defined in theInput Datadialog, the "unused" joints can be displayed on the stereonet in gray. You can toggle the display of the unused joints on the stereonet on or off in theDisplay Optionsdialog. SelectDisplay Options, and under theGenera...
The AHP–EW method is a comprehensive weighting method combining the analytic hierarchy process and entropy weight methods, which is used to establish the hierarchical analysis model between system reliability and multiple failure criteria. By considering the joint failure of multiple failure modes in ...
[38] studied the effect of loading rate on the crack propagation and failure modes of the specimen under uniaxial loading. To ensure that the numerical model maintains static equilibrium during the loading process, the displacement loading rate of the numerical model is taken as 0.08 m/s. In ...
Modeling fibers explicitly allows the capture of the full multi-cracking characteristics, including crack spacing, crack width and overall response as well as the complete failure modes of fiber reinforced composites, in a natural way. However, the explicit modeling of millions of discrete fibers ...
After the initiation of cracking, the load increment was increased to 5 kN. Strain in the main steel reinforcement (mild steel and strand) and the mid-span deflection were monitored during testing. 3 Experimental results and discussion 3.1 Ultimate loads and failure modes The failure load was ...
