Energy is an internal variable during rock deformation and failure, its dissipation conversion law can reflect the rock’s damage deterioration state. Analysis of failure process from perspective energy helpful to deeply understand mechanism damage, fracture instability has important theoretical practical significance for stability evaluation support control surrounding rock. In this study, thro...

The main object of this paper is to introduce and study a new concept of f-Wijsman lacunary statistical convergence of sequences of sets, where f is an unbounded modulus. The definition of Wijsman lacunary strong convergence of sequences of sets is extended to a definition of Wijsman lacunary strong convergence with respect to a modulus for sequences of sets and it is shown that, under certain ...

The purpose of this present paper is to give an equivalent theorem on Lupaş operators with ω φλ(f, t), where ω r φλ(f, t) is Ditzian-Totik modulus of smoothness for linear combination of Lupaş operators.

It is an effective method to prepare geopolymer with recycled brick and concrete fine powder (RP) slag as main materials for the resource utilization of construction waste. However, its hydration products have large drying shrinkage high efflorescence risk under normal curing conditions. Until now, durability powder–slag-based (RPSG) has not been well documented, such efflorescence. In this stu...

Roads are subjected to vehicle traffics with different loads and velocities. Geogrid reinforcement is of the best methods for road improvement due to the ease of construction, delay in damage development and financial efficiency. This study evaluates pavement response under different loads and velocities, before and after geogrid reinforcement. A finite element software (ABAQUS) is used for num...

seismic ground motion is profoundly affected by geometrical and mechanical properties of soil deposits overlaying bedrock. local seismic ground response of saturated soil deposits was studied in literature by applying the effects of soil stress state and index properties on the strain-dependent normalized shear modulus reduction, g/g0, and damping ratio, d, curves in an equivalent linear analys...

This paper proposes a concise concept for quantifying the shear/torsional stiffness of laminated glass beams experimentally by introducing Equivalent-Sectional Shear Modulus (ESSM), that is directly measured from torque and sectional-rotation correlation with torsion test tailor-made photogrammetry technique. The advantage this method originated measuring overall rotation to response beam altog...

Coal body is a type of fractured rock mass in which lots of cleat fractures developed. Its mechanical properties vary with the parametric variation of coal rock block, face cleat and butt cleat. Based on the linear elastic theory and displacement equivalent principle and simplifying the face cleat and butt cleat as multi-bank penetrating and intermittent cracks, the model was established to cal...
