2. Investigating physical, mechanical and crack properties of granite in the fatigue process

Shahram Ghasemi; Mashalah Khamehchiyan; Mohammad Reza Nikudel; Ahmad Zalooli

Volume 31, Issue 2 , Summer 2021, Pages 1-10

http://dx.doi.org/10.22071/gsj.2020.221737.1765

Abstract
  Joints and cracks are an integral part of rock structures. When load applied to these structures, growth, and interaction of the cracks lead them to failure. This aspect is particularly crucial in cyclic loading because failure occurs at stress levels lower than the yield point due to the fatigue process. ...  Read More
