On the effect of grain size on rock behavior under cyclic loading by distinct element method
It is well-known that the mechanical behavior of rocks under cyclic loading is much different from static loading conditions. In most constructions, the load applied to structures is within dynamic ranges. That’s why a great deal of attention has been paid towards this field in order to identify the dynamic behavior of rocks in more details. Nevertheless, the nature of dynamic failure in rocks ...
متن کاملNumerical assessment of influence of confining stress on Kaiser effect using distinct element method
Nowadays acoustic emission (AE) testing based on the Kaiser Effect (KE) is increasingly used to estimate the in-situ stress in laboratories. In this work, this effect is assessed on cylindrical specimens in numerical simulations of the cyclic loadings including loading, unloading, and re-loading cycles using a 3D code called the particle flow code (PFC) based upon the distinct element method. T...
متن کاملDeformation Behavior of Human Dentin under Uniaxial Compression
Deformation behavior of a human dentin under compression including size and rate effects is studied. No difference between mechanical properties of crown and root dentin is found. It is mechanically isotropic high elastic and strong hard tissue, which demonstrates considerable plasticity and ability to suppress a crack growth. Mechanical properties of dentin depend on a shape of samples and a d...
متن کاملHigh strain-rate behavior of ice under uniaxial compression
In the present study, a modified split Hopkinson pressure bar (SHPB) is employed to investigate the dynamic response of ice under uniaxial compression in the range of strain rates from 60 to 1400 s 1 and at initial test temperatures of 10 and 30 C. The compressive strength of ice shows positive strain-rate sensitivity over the range of strain rates employed; a slight influence of ice microstruc...
متن کاملDistinct element modelling of the mechanical behaviour of intact rocks using voronoi tessellation model
This paper aims to study the mechanical behaviour and failure mechanism of intact rocks under different loading conditions using the grain based model implemented in the universal distinct element code (UDEC). The grain based numerical model is a powerful tool to investigate complicated micro-structural mechanical behaviour of rocks. In the UDEC grain based model, the intact material is simulat...
