In this paper, a new solution of the stress intensity factors (SIFs) for two unequal collinear cracks is developed considering internal pressure, friction and compressive stress. The complex stress function and elliptic integral function are used to

The former studies indicate that loading rates significantly affect dynamic behavior of brittle materials, for instance, the dynamic compressive and tensile strength increase with loading rates. However, there still are many unknown or partially unkn

Concrete structures usually contain cracks or microcracks. Under dynamic loading, such as impacts, blasts and earthquakes, these cracks may initiate and propagate, weakening concrete strength and structure’s stability. It is thus necessary to carry

Drilling and coal sampling is the necessary prerequisite to determine the parameters of prediction and prevention for coal and gas outburst in underground coal mine. The integrity of samples is very important for the prediction of parameters. Therefo

In the process of tunnel blasting excavation, radial cracks could be induced. To investigate the effect of loading rates on crack propagation velocity and rock initiation toughness, a new cracked tunnel specimen was proposed in this paper, and drop w

An accurate model of gas desorption and diffusion is the necessary prerequisite to accurately predict gas transfer and evaluation of gas content in the coal. A new modified shrinking core model was proposed and modified based on the shrinking core mo

Accurate measurement of gas pressure during canister desorption of coal cuttings is an important foundation to prevent coal gas dynamic hazards and determine gas content of coal by volumetric method. It was a new finding that gas pressure in the insu
