The stress-strain behaviour of jointed chalk. By M.J. Millar. Abstract. SIGLEAvailable from British Library Document Supply Centre-DSC:DXN / BLDSC - British Library Document Supply CentreGBUnited KingdoAuthor: M.J. Millar. This approach simulated the jointed rock mass as an assembly of fractures embedded into the rock SRM samples were submitted to uniaxial loading, and the complete stress–strain. The rock mechanical models presented account for the influence of discontinuities on the stress-strain behavior and the permeability of jointed rock masses. This book is for: Civil- and Mining-Engineers - Geologists - Students in the related fields. This approach simulated the jointed rock mass as an assembly of fractures embedded into the rock matrix. The SRM samples were submitted to uniaxial loading, and the complete stress–strain behaviour of each specimen was recorded. This approach provided a way to determine the complex constitutive behaviour of large‐scale rock mass by: 8.
The input variables used for predicting the stress–strain response of jointed rocks are confining pressure (σ3), uniaxial compressive strength of intact rock (σci), joint frequency (Jn) joint orientation (β), joint inclination parameter (n), joint roughness parameter (r) and axial strain ( Cited by: The relative merits and limitations of both these approaches in predicting the stress-strain response of jointed rocks are brought out through these numerical simulations. 1 Rubber Elasticity: Basic Concepts and Behavior 3 2These are (poor) for the effective length l of a freely jointed link for the real molecular , stress–strain curve of a corresponding unﬁlled vulcanizate.

Such a material iselastic accordingtothedescription ofelasticity given earlier (immediate response,fullrecovery), andit is also linear in its relation between stress and strain (or equivalently, force and deformation).

PFC 3D is used to study the mechanical behavior of blocks with finite size joints. • UCS B and DM B depend heavily on the joint dip angle (β) & joint size (k). • Jointed blocks produced three types of stress–strain curves (Types I–Type III). • A relation exists between the types of curves and β and k values. •Cited by: In the rock engineering, joints have significant effect on the stress-strain relationship of jointed rock mass. Generally speaking, there are two categories of approaches: the first method is that joint element is utilized to simulate jointed rock by: 5. The stress-strain graph provides engineers and designers a graphical measure of the strength and elasticity of a material. It allows them to predict the behavior of materials used in a given application. To draw the graph, the material must first undergo a tensile test. A tensile test is the simplest and most widely implemented mechanical test.
