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 …

I put on my researching hat and dove into the question of what the strongest rock is and why. The strongest rock in the world is diabase, followed closely by other fine-grained igneous rocks and quartzite. Diabase is strongest in compression, tension, and shear stress. If mineral hardness is the determining factor of strength then diamond is ...

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 …
