A strain-based criterion for failure load prediction of steel/CFRP double strap joints
Razavi, Seyed Mohammad Javad; Ayatollahi, Majid Reza; Majidi, Hamid Reza; Berto, Filippo (Journal article, 2018)One of the most effective approaches to improve the strength of steel structures is using the carbon fiber reinforced polymer (CFRP) as externally-bonded sheets. In this paper, a strain-based failure criterion, namely the ... -
Averaged strain energy density criterion for rupture assessment of cracked rubbers: A novel method for determination of critical SED
Heydari-Meybodi, Mahdi; Ayatollahi, Majid Reza; Berto, Filippo (Journal article; Peer reviewed, 2018)In the present study, the application of averaged strain energy density (ASED) criterion has been extended to hyperelastic materials. Because of the material and geometry nonlinearities, commonly known for rubber-like ... -
Rapid Strain Energy Density evaluation for V-notches under mode I loading conditions
Foti, Pietro; Berto, Filippo; Ayatollahi, Majid Reza (Peer reviewed; Journal article, 2020)This work investigates the possibility to evaluate the Strain Energy Density value with a free mesh model suggesting the use of a correcting formula a posteriori. Several numerical analyses were carried out to prove the ...
