Study on fracture parameter calibration and failure characteristics of rock with hole and crack
Deep Underground Science and Engineering, EarlyView.The SIF and plastic zone equations for a single hole and crack have been derived. The model's failure state leads to the identification of four types of cracks. The plastic zone increases with increased brittleness and decreased crack length. Abstract Cracks within the surrounding rock of roadways significantly affect their stability and failure ...

Review of the relationship between aggregates geology and Los Angeles and micro-Deval tests
Bulletin of Engineering Geology and the Environment, 2021 Rock aggregates constitute the enormous volume of inert construction material used around the globe. The petrologic description as igneous, sedimentary, and metamorphic types establishes the intrinsic formation pattern of the parent rock. The engineering

Subaqueous “yardangs”: analogs for aeolian yardang evolution
, 2013 Landforms, morphologically similar to aeolian yardangs but formed by erosion of bedrock by currents on an estuarine rock platform, are described for the first time. The geometries of the “yardangs” are described and related to semi-lemniscate shapes that

Wind transport of foraminiferal tests into subaerial dunes: an example from western Ireland
Journal of Micropalaeontology, 2009 INTRODUCTION The empty tests of dead foraminifera behave as sedimentary particles and are subject to transport, although their different shapes and effectively low density means that their hydraulic equivalence is greater than that of spherical quartz ...
