It is pointed out that hydrostatic stress has effects upon shear slip as well as original strength of material, and a shear strength formula is obtained which takes into account the influence of intermediate principal stress on shear strength.

The iterative method and VB-5 computer program are applied to solve the equations, and the typical relationship curves about shear slip failure of the rock around borehole are drawn out.

According to the three dimensional elastic equilibrium equations and the conditions of interfacial shear slip, a model of interfacial shear slip of laminated composite plates is developed.

Introduce anchor cable for two times high-pressure splits grouting craft at the landslide strong decayed mudstone & broccia, Raise completely soil body of C and ψ and shear slip surface of normal pressure δ and superficial area A for anchor from the macroscopic and tiny. Thus raise bearing capacity for anchor cable of action mechanism.

In general machining condition (a_p=0.3,0.7mm), the deformation of chip results from deformation on neighbouring lamellas and from shear slip on crystal face within a lamella.

The discriminating discipline for the high slope stability based on the monitoring deformation result, and the quantitative evaluation method based on shear slip, axial force and horizontal pushing force for the stability of high slope are suggested in the article. [

However, the difference is that the continuous composite slab can carry further substantial load even after the shear slip initiation as against the simply supported slab.

It is apparent, also, that further investigation is required to determine how consistent rules can be established to link micro-failure criteria to equivalent macro-strength and toughness properties for a macro-shear slip surface.

The tangential displacement vector has non-vanishing components in both directions, parallel as well as perpendicular to the imposed uniform shear slip, the first being predominant on the second.

Here we focused on fractures which are critically-stressed, causing shear slip in a current stress field.

The effects of shear slip on the response of angle- and cross-ply laminated plates subjected to different edge boundary conditions are finally studied by means of corresponding numerical results that are obtained, presented and discussed.

Being an extension of a relevant model that deals with perfectly bonded laminates, this study accounts further for the effects of shear slip by introducing appropriate interfacial bonding conditions.

In the practical application of engineering, many rock foundations possess a certain extent of the layered phenomena. When forces are applied in a direction parallel or perpendicular to the layered surfaces, these rock foundations present different physical and mechanical properties. Briefly, a favorable result cannot be obtained if treating it simply as an isotropic and homogeneous material. Therefore, we would prefer to treat the layered rock foundations as inhomogeneous materials in opposite.After a brief...

In the practical application of engineering, many rock foundations possess a certain extent of the layered phenomena. When forces are applied in a direction parallel or perpendicular to the layered surfaces, these rock foundations present different physical and mechanical properties. Briefly, a favorable result cannot be obtained if treating it simply as an isotropic and homogeneous material. Therefore, we would prefer to treat the layered rock foundations as inhomogeneous materials in opposite.After a brief description of the elastic matrix, stress matrix and stiffness matrix, the elasto-plastic matrices and the matrices both in tension failure and in shear slip are derived. Thereby, a computer program for solving the two-dimensional problems of layered rocks is compiled. The stresses and strains in the layered foundations of tunnels and underground structures of hydro-electric power plants then can be analyzed and solved.

Based on shaking table tests and system identification, the nonlinear mathematical models for unreinfoiced concrete block masonry building are presented in this paper. Analysis results show that the "semi-degrading tri-linear" model of restoring force can be only fitted to cracking building, and the"shear-slip" restoring force model can be used to predict the seismic response of masonry building during failure stage.

The gravity gliding structures are widely spreaded in the coal fields in China. Based on the structural environment, the relationship among the strata, rock composition and texture, tectonic deformational characters, moving manner of glided nappe, slipping distance and velocity, origin of the glide fault, and mechanism of gliding deformation, the author classifies the gravity gliding structures in China into five types as follows: the brittle fracture slip-fall with a rapid velocity, the rigid mass slip-rub...

The gravity gliding structures are widely spreaded in the coal fields in China. Based on the structural environment, the relationship among the strata, rock composition and texture, tectonic deformational characters, moving manner of glided nappe, slipping distance and velocity, origin of the glide fault, and mechanism of gliding deformation, the author classifies the gravity gliding structures in China into five types as follows: the brittle fracture slip-fall with a rapid velocity, the rigid mass slip-rub with a relative rapid velocity, the plastic shear slip-move with a slow or rapid velocity, the viscoplastic slip-flow with a relative slow velocity, and viscous rheid slip-fold with a slow velocity. Their mechanical models can be expressed separately by use of the constitutive equation of elastic Hookians body (type one and two), plastic St. Venant body (type three), viscoplastic Bingham body (type four), and viscous Newtonian body (type five). The distribution of stress and process of mechanics in different parts of a gravity structure are represented by the result of a finite element calculation of gravity structure and the analyses of Mohr circle about the relationship between fault and stress axes.
