Study on the mechanical traits, failure mechanisms, energy responses, and influencing factors of columnar jointed basalts under direct and indirect tensile conditions

Frontiers in Earth Science
In this study, by merging mesoscopic damage mechanics, the probabilistic strength principle, and continuum mechanics, the visuals of columnar jointed basalts (CJBs) featuring various joint arrangement patterns are converted into inhomogeneous numerical ...

Splitting tensile strength of shale cores: intact versus fractured and sealed with ureolysis-induced calcium carbonate precipitation (UICP)

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
Ureolysis-induced calcium carbonate precipitation (UICP) is a biomineral solution where the urease enzyme converts urea and calcium into calcium carbonate.

Soil Fragmentation and Friability. Effects of Soil Water and Soil Management [PDF]

, 2002
Soil fragmentation is a primary aim in most tillage operations in order to create a soil environment favourable for crop establishment and growth. Soils vary around the world from those exhibiting a self-mulching nature to those of a hardsetting nature ...

Tensile strength of compacted soil

, 2018
Tensile strength of soil is important for many earth slopes and retaining structures. With the formation of tensile cracks, the permeability of soils is greatly increased, and it can result in the failure of the earth retaining structures during raining ...
