Cemented rock fill (CRF) is commonly used in cut-and-fill stoping operations underground mining. This allows for the maximum recovery of ore. Backfilling can improve stope stability workings and then ground whole mine site. However, backfilling step scenarios vary from site to paper presents investigation five different their impacts on stopes at four mining levels. A comprehensive comparison d...

it is difficult to develop an algorithm which is able to generate the appropriate mesh around the interfaces in bimaterials. in this study, a corresponding algorithm is proposed for this class of unified structures made from different materials with arbitrary shapes. the non-uniform mesh is generated adaptively based on advancing front technique available in abaqus software. implementing severa...

Healthy eyes are vital for a better quality of human life. Historically, for man-made materials, scientists and engineers use stress concentration factors to characterise the effects of structural non-homogeneities on their mechanical strength. However, such information is scarce for the human eye. Here we present the shear stress distribution profiles of a healthy human cornea surface in vivo ...

Structural components subjected to high frequency vibrations, such as those used in vibrating parts of gas turbine engines, are usually required to avoid resonance frequencies. Generally, the operating frequency is designed at more than resonance frequencies. When a vibrating structure starts or stops, the structure has to pass through a resonance frequency, which results in large stress concen...

An evaluation model of aluminum alloy welded joint low-cycle fatigue data based on information entropy is proposed. Through calculating and analyzing the information entropy of decision attributes, quantitative contribution of stress concentration, plate thickness, and loading mode to the fatigue destruction are researched. Results reveal that the total information entropy of the fatigue data b...

Surface cracks in butt-welded joints usually occur places with increased stress concentrations. The concentration factor (SCF) can be calculated using an empirical equation, five geometric parameters of a joint (thickness the base material, toe radius, weld angle, width, and reinforcement height). However, industrial environment, it is impractical sometimes even impossible to measure all suffic...
