A. Dadi-givshad; M. Ahmadi; H. R. Nejati

Volume 11, Issue 2 , April 2020, , Pages 433-451

http://dx.doi.org/10.22044/jme.2020.7864.1650

Abstract
  One of the methods used to investigate the damaged zone in rock structure is the acoustic emission method. This method is based on receiving the elastic waves that are produced by deformation and cracking of the rock mass around the underground excavation. In this research, a study is conducted on the ...  Read More

A new brittleness index for estimation of rock fracture toughness

H. R. Nejati; Seyed A. Moosavi

Volume 8, Issue 1 , January 2017, , Pages 83-91

http://dx.doi.org/10.22044/jme.2016.579

Abstract
  Assessment of the correlation between rock brittleness and rock fracture toughness has been the subject of extensive research works in the recent years. Unfortunately, the brittleness measurement methods have not yet been standardized, and rock fracture toughness cannot be estimated satisfactorily by ...  Read More
