“…The present study reviews the published research results of the equation proposed by Moradkhani et al [ 47 ] to estimate the K IFR value using irregular and branch micro-cracks. It is based on measuring the K IFR / K IC of brittle materials, at the lowest cost and, at the same time, the simplicity of the test steps [ 28 ]. In the last decade, ranges of brittle materials were tested with the aim of measuring the accuracy and benchmarking the accuracy of the equation outputs with various fabrication conditions, and satisfactory results were obtained [ 42 ].…”

“…Methods such as Chevron Notch Beam (CNB) [ [11] , [12] , [13] ], Single-Edge Pre-cracked Beam (SEPB) [ 13 , 14 ], Single Edge Notch Beam (SENB) [ 14 , 15 ], Single Edge V-notch Beam (SEVNB) [ 16 , 17 ], Single Edge Laser Notch Beam (SELNB) [ 18 , 19 ], Double Cantilever Beam (DCB) [ [20] , [21] , [22] , [23] ], Wedge-insert Double Cantilever Beam (WDCB) [ 20 , 22 , 23 ], and End-Loaded Split (ELS) [ 24 , 25 ] are some of these techniques, and many of these methods have been used for many years to determine the K IC or K IFR of materials. In comparison, CFM is based on sharp indenters such as Vickers [ [26] , [27] , [28] , [29] , [30] ], Knoop [ [31] , [32] , [33] ], Berkovich [ 34 , 35 ], and Conical [ 36 ], which are applied to the sample in a certain period and amount of loading and are often used for brittle materials [ 34 , 36 ]. In general, the application of these techniques in the two groups varies according to the material, the manufacturing costs and testing of samples, and the required accuracy [ 3 ].…”
