Davood Fereidooni received his Ph.D. (2014) degree in Engineering Geology (Geological Engineering) from Bu-Ali Sina University, Hamedan, Iran, where he studied as a Ph.D. student from September 2009 to January 2014. He received his B.S. (2000) degree in Geology and M.S. (2004) in Engineering Geology, from Shahroud University of Technology and the Bu-Ali Sina University, respectively. He serves on School of Earth Sciences of Damghan University from 2014 to present as Assistant Professor of Engineering Geology. Through his research and consulting, Dr. Davood Fereidooni made seminal contributions in the areas of engineering geology and rock mechanics. He has innovated an apparatus and method for assessing durability of rocks, known as the “Durability Test Apparatus of Rock Subjected to Rainfall”. He is an author with a list of fundamental and advanced text books, including General and Engineering Geology (2009; 2014); Principle of Rock Slope Engineering (2015); and Engineering Geology for Geology Students (2017). He has also authored or co-authored more than 50 technical papers for journal and conference publications.

In this research, different experimental techniques have been used to determine the strength of five types of anisotropic foliated rocks, selected from the Hamedan Province, west of Iran. For this purpose, after sample preparation and assessment of mineralogical and physical properties, selected samples were subjected to Cylindrical Punch, Point Load and Brazilian tests and their strengths were evaluated with respect to different angles between anisotropy planes and the major loading directions. Data analyses show that the types and amounts of minerals have an influence on the physical and mechanical properties of the tested anisotropic rocks. Porosity and water absorption also have a dominant control on the mechanical indices such as cylindrical punch index (CPI), point load index (Is(50)) and Brazilian tensile strength (BTS). On the basis of the test result, two empirical equations are proposed for calculating CPI and Is(50). Other empirical equations relating studied indices are also presented.
