Constitutive Modeling of Rocks, Rock Joints and Rock Masses including Strain Softening Behaviour
The rocks are formed through very complex processes and the complex behaviour of rock masses is dominated by the planes of weaknesses . Rock mass consists of intact rock and discontinuities. Many rocks show strain softening behaviour under loads. In this paper, the constitutive models for intact rocks and rock joints are presented. These form the basis for the development of constitutive models...
متن کاملShear Strength of Rock Joints Based on Quantified Surface Description
One of the primary objectives of this work is to better understand the frictional behavior of joints under shear loads, including the creation of damage zones. Discontinuities have an important influence on the deformational behavior of rock systems. The choice of a general criterion to determine the shear strength of rough rock joints is a general problem that has been investigated for many ye...
متن کاملApplication of Schmidt rebound number for estimating rock strength under specific geological conditions
A literature review revealed that most of the empirical equations introduced for determination of the uniaxial compressive strength (UCS) of rocks based on the Schmidt hammer rebound number (N) are not sufficiently reliable mostly due to the relatively low coefficient of correlations. This is attributed to the fact that in most cases one formula is used for all types of rocks, altho...
متن کاملInvestigation on Tensile Strength of Friction Stir Welded Joints in PP/EPDM/Clay Nanocomposites
Polymer-based nanocomposites due to their advantages such as corrosion resistance,adequate mechanical properties and low cost are widely used in modern technologies. The increasing application of these nanocomposites, and hence their welding seems unavoidable. In this paper, a novel hottool in friction stir welding process is used for butt welding nanocomposite plates of 5 mm thick containing p...
متن کاملeffect of gap distance on tensile strength of preceramic base metal solder joints
background and aims. in order to fabricate prostheses with high accuracy and durability, soldering techniques have been introduced to clinical dentistry. however, these prostheses always fail at their solder joints. the purpose of this study was to evaluate the effect of gap distance on the tensile strength of base metal solder joints. materials and methods. based on ada/iso 9693 specifications...
