• A synthesis of geometry effect on brittle fracture 

      Razavi, Seyed Mohammad Javad; Ayatollahi, Majid reza; Berto, Filippo (Journal article, 2018)
      There are numerous analytical solutions in order to take into account the geometry effect on the fracture toughness and the fracture load of the cracked specimens. However, due to the complexities of the mentioned criteria ...
    • Assessment of mixed mode fatigue crack growth under biaxial loading using an iterative technique 

      Razavi, Seyed Mohammad Javad; Ayatollahi, Majid reza; Berto, Filippo (Peer reviewed; Journal article, 2020)
      Crack growth is investigated numerically in a cruciform specimen with an inclined center crack subjected to biaxial fatigue loading. The mixed-mode fatigue crack growth was examined using a parametric study both on the ...
    • Effects of different indentation methods on fatigue life extension of cracked specimens 

      Razavi, Seyed Mohammad Javad; Ayatollahi, Majid reza; Amozadi, Atefeh; Berto, Filippo (Journal article; Peer reviewed, 2018)
      In this paper, 3 different indentation methods have been investigated for crack arresting and fatigue life enhancement of cracked components. The influence of residual stresses induced by indentation on fatigue crack growth ...
    • Numerical Evaluation of T-stress under Mixed Mode Loading Through the Use of Coarse Meshes 

      Acanfora, M; Gallo, Pasquale; Razavi, Seyed Mohammad Javad; Ayatollahi, Majid reza; Berto, Filippo (Journal article; Peer reviewed, 2018)
      The present paper investigates the employment of coarse meshes in evaluating the T-stress with the displacement method. Several finite element analyses have been carried out with different mesh refinements and accuracies. ...
