A Flat-Jointed Bonded-Particle Material For Hard Rock
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 introducing a polygonal …

Rock-Strength Data From Cores and Logs
Rock Strength From Core Tests. Often, samples for rock-mechanics testing are taken only after the initial slab cut is made. This process reduces the core diameter and, hence, the plug length, usually making the length/diameter ratio unacceptable. It is even worse when no samples for rock-mechanics tests are cut and the core is allowed to dry ...

Strength and Deformation Characteristics of Rocks
The tangent modulus E t is generally chosen as the slope of the tangent line of the stress–strain curve at the origin or at the point where the stress is half the strength of the rock sample. The secant modulus E s is mostly used as the ratio of stress to strain when the stress is half the strength of the rock sample, i.e., E 50, also known as the …
Iron rock
When the Al Kharid resource dungeon was added, the rocks were rearranged.
