The Methodology for the Young Modulus Derivation for Rocks

The basic strength laboratory test for rocks is a uni-axial compression. Every rock behaves elastically up to the point when propagated cracks change the manner of deformation into quasi-plastic and, reaching peak strength, a rock starts to break down, changing its strength properties.

Effect of length-to-diameter ratio on the unconfined

Dec 24, 2015 · Abstract. In this work, the influence of the length-to-diameter ratio (L/D) on the unconfined compressive strength (UCS) of cohesive soil specimens was assessed.An L/D ratio of between 2 and 3 is generally recommended by accepted scientific and technical authorities. Nevertheless, published reports on the effect of specimen shape on soil strength are scarce.

Unconfined Compression Strength Correlation with Shear

Apr 06, 2010 · I am trying to come up with an appropriate value of unconfined compression strength of the granodiorite noted at the site to backcheck my design against the other data we got from the investigation. The rock was noted at the bottom of several hollow stem auger boring that were conducted. The shear wave velocity was 5600, and 5900 ft/s.
