Research on Damage Evolution Mechanism of Layered Rock Mass under Blasting Load
BuildingsRock mass consists of many discontinuities, such as faults, joints, etc., and layered joints are a common kind of rock mass structure. The joints affect the stress wave propagation, and blasting is an economical and efficient rock fragmentation method ...

Shear creep characteristics and constitutive model of hidden non-persistent joints
Yantu gongcheng xuebao, 2019 The joints control the boundary of the rock slope instability. A large number of joints in the natural world are not completely persistent, and are hidden inside the slope.

Advanced Materials, EarlyView.The Y supersaturation in the [Ba‐Cu(I/II)‐O] transient liquid composition is the driving force toward YBCO nucleation and growth in TLAG. Tuning the initial (Ba:Cu) molar ratio in the ink composition determines the YBCO epitaxial nucleation through supersaturation control.

Mechanisms of failure of jointed rock masses and the behaviour of steep slopes [PDF]
, 1998 The geomorphological behaviour of steep jointed rock slopes has been studied using distinct element method computer models. In order to model steep slopes effectively, methodologies need to be combined from the studies of environmental modellers ...

Elastic moduli for fractured rock mass
, 2013 The presence of joint discontinuities has long been recognized as an important factor influencing the mechanical behavior of rock masses. This paper proposes a stress-strain model for an assemblage of intact rock blocks separated by joint planes.
