Evaluating Microscale Failure Response of Various Weathering Grade Sandstones Based on Micro-Scale Observation and Micro-Structural Modelling Subjected to Wet and Dry Cycles

Kausar Sultan shah; Mohd Hazizan bin Mohd Hashim; Hafeez Ur Rehman; Kamar shah bin Ariffin

Volume 13, Issue 2 , April 2022, , Pages 341-355


  The significance of rock failure can be found from the fact that microfracture genesis and coalescence in the rock mass results in macroscale fractures. Rock may fail due to an increase in the local stress, natural fractures, weathering inducing micro-crack genesis, coalescence, and propagation. Therefore, ...  Read More

Application of Stochastic Simulation in Assessing Effect of Particle Morphology on Fracture Characteristics of Sandstone

K. Sultan shah; M. H. bin Mohd Hashim; H. Rehman; K. S. bin Ariffin

Volume 12, Issue 4 , October 2021, , Pages 969-986


  Indirect tensile testing is used in order to investigate the effect of particle morphology (shape and size) on the various weathering grade sandstone fracture characteristics. Several fracture characteristics are discussed in depth in this work including the fracture length (FL), fracture deviation area ...  Read More

Monte Carlo Simulation-Based Uncertainty Integration into Rock Particle Shape Descriptor Distributions

K. Sultan Shah; M. H. Bin Mohd Hashim; K. Sh. Bin Ariffin

Volume 12, Issue 2 , April 2021, , Pages 299-311


  The particles within the rock samples are present in extensive ranges of shapes and sizes, and their characterization and analysis exist with a considerable diversity. The prior research works have appraised the significance of the particle shape types and their effects on the geotechnical structures ...  Read More

Effect of freeze-thaw cycle on strength and rock strength parameters (A Lushan sandstone case study)

M. Hosseini; A. R. Khodayari

Volume 10, Issue 1 , January 2019, , Pages 257-270


  In an era of continued economic development around the globe, numerous rock-related projects including mining and gas/oil exploration are undertaken in regions with cold climates. Winters in the Iranian western and northwestern provinces are characterized by a high precipitation rate and a cold weather. ...  Read More

Rock Mechanics
Effects of temperature and confining pressure on mode II fracture toughness of rocks (Case study: Lushan Sandstone)

M. Hosseini; A. R. Khodayari

Volume 9, Issue 2 , April 2018, , Pages 379-391


  The fracture mechanics examines the development and expansion of cracks in solids and how they affect the deformation of materials. The stress intensity factors at the tip of the crack and the critical stress intensity factors or fracture toughness of materials are considered in the relevant criteria. ...  Read More
