determining the fracture toughness of brittle materials, it&#8217;s critical to select the correct equations according to the crack morphology and material characteristics to calculate the fracture toughness. Indentation fracture toughness test is to estimate the KIC of materials by using the cracks generated by Vickers hardness indentation. These cracks were formed by applying a high load to a small piece of test material using a Vickers hardness
