• Brittle fracture prediction of key-hole notched specimens by means of J-integral expression 

      Razavi, Seyed Mohammad Javad; Majidi, Hamid reza; Berto, Filippo (Peer reviewed; Journal article, 2020)
      The main goal of the present research is to check if J-integral criterion is capable of predicting the onset of brittle fracture in key-hole notched isostatic poly-granular graphite plates. In this way, this article provides ...
    • Fracture assessment of U-notched graphite specimens by means of cohesive zone model 

      Razavi, Seyed Mohammad Javad; Majidi, Hamid reza; Berto, Filippo; Ayatollahi, Majid reza (Peer reviewed; Journal article, 2020)
      Various types of graphite have gained interest in many industrial applications due to their high strength and excellent heat tolerance. However, due to the brittle nature of this material, presence of stress concentrators ...
