Jointed materials
NettetDuring direct shear tests of jointed sandstone samples containing non-connected joints, after the peak shear strength, formation for penetrating rough-walled fractures resulted … NettetThe jointed material model is intended primarily for applications where the stresses are mainly compressive. The model provides a joint opening capability when the stress normal to the joint tries to become tensile. In this case the stiffness of the material normal to …

The geological causes include bedding, faults, unconformity, weak materials, sheared or jointed materials, and weathered …
NettetStainless steel joints shall be welded, assembled with approved tubing fittings, brazed with a material having a melting point in excess of 1000°F (538°C), or assembled with press-connect fittings listed to CSA LC 4, Press-Connect Metallic Fittings for Use in Fuel Gas Distribution Systems. Nettet1. sep. 1993 · In this paper, the characteristics of the stress field near a corner of jointed dissimilar materials are studied as a plane problem. It is found that the order of singularity is dependent not only on the elastic constants of materials and the local geometry of corner, but also on the deformation mode.
Nettet24. jun. 2012 · ABSTRACT:. The bonded-particle model (BPM) consisting of parallel-bonded disks or spheres suffers from the limitation that if one matches the unconfined-compressive strength ( ) of a typical hard rock, then the direct-tension strength ( ) of the model will be too large. This limitation can be overcome in two dimensions by … NettetIn the continuum models, the jointed rock mass is treated as a continuum with equivalent material properties which reflect the effect of the joints. This approach circumvents some of the difficulties in the discrete …
