Joint characteristics . Introduction . There is a difficulty in giving a concise definition of what constitutes a joint. Over the years there have been several discussions whether 'joint', 'fracture' or other terms should be preferred in rock mechanics, engineering geology and rock engineering. ISRM (1975) has chosen 'joint' defined as: "Joint
The rock tends to expand upward and does so by forming roughly horizontal joints. Secondly, residual stresses may be locked into rocks at the time of formation, …

The paper focuses on the methods commonly used for measuring and quantifying the joint roughness in the current rock mass characterization practice. Among the different parameters traditionally …
Joint work is work that is made by more than one creator. A creation that is deemed a joint work holds significant legal implications because all creators can claim ownership rights over the creation. Indeed, creators of joint works hold undivided interests in the creation despite any differences in each creator's contribution.
Learn about the main features and characteristics of joints and jointing in rock masses, such as planarity, smoothness, condition, size, continuity, orientation, pattern, and …

Toggle Joint. Simple Mechanisms. A link mechanism commonly known as a toggle joint is applied to machines of different types, such as drawing and embossing presses, stone crushers, etc., for securing great pressure. The principle of the toggle joint is shown by Fig. 1. There are two links, b and c, which are connected at the center.
A 2D joint geometry generation code was used to generate finite size actual joint networks in 2D rock blocks. A 2D distinct element code (UDEC) was chosen as the stress analysis tool in this study. Fictitious joints were introduced into the rock blocks which contain finite size actual joints to discretize the problem domain into polygons.
Igneous rock is a category of rock formed through the cooling and solidification of magma, which is molten rock that originates from the Earth's mantle. This process, known as igneous differentiation, results in the formation of a wide range of rock types, including igneous intrusives and igneous extrusives.

The current theories dealing with the mechanics of joint development are discussed critically. An analysis of the stress conditions which can exist in competent rocks in the crust is presented. The conclusion is reached that "Master" and "Regional" Joints can be, generically, either "tensional" or "shear" structures.
ADVERTISEMENTS: In this article we will discuss about:- 1. Origin of Joints 2. Classification of Joints 3. Occurrence of Joints 4. Engineering Considerations for Joints in Rocks. Origin of Joints: Joints are caused in different rocks due to different reasons. No single theory can, explain origin of all types of joints. At present it is […]

In this paper, artificially prepared jointed rock masses with different joint surface characteristic were used to perform multiple shear tests to obtain corresponding shear strength data. The research results showed that there were obvious relations between the shear strength of the joint surface morphology.
