Evolution of Crack Tip Constraint in a Mode II Elastic-Plastic Crack Problem
Ayatollahi, MR; Berto, Filippo (Journal article, 2018)Numerous studies have shown that crack tip constraint has an important effect on the level of conservatism when crack extension is investigated in elastic-plastic fracture mechanics. Constraint effect has been explored ... -
Mixed-mode (I/II) rupture assessment of rubber-like materials weakened by cracks using the averaged strain energy density criterion
Heydari-Meybodi, M; Ayatollahi, MR; Berto, Filippo (Journal article, 2018)In the present study, the application of the averaged strain energy density (ASED) criterion is extended from pure mode-I to mixed-mode (I/II) loading for hyperelastic materials. Indeed, the use of a recently proposed ... -
Review of the influence of non-singular higher order terms on the stress field of thin welded lap joints and small inclined cracks in plates
Berto, Filippo; Ayatollahi, MR; Vantadori, S; Carpinteri, A (Journal article; Peer reviewed, 2017)In stress analysis of cracked plates, alongside the stress intensity factor which quantifies the singular stress component perpendicular to the crack plane, the role played in crack growth by the constant term parallel to ... -
Rupture analysis of rubber in the presence of a sharp V-shape notch under pure mode-I loading
Heydari-Meybodi, M; Ayatollahi, MR; Berto, Filippo (Journal article, 2018)The rupture behavior of styrene-butadiene rubbers (SBR) in the presence of a V-shape notch is investigated for the first time both experimentally and theoretically. In the experiments, V-notched samples of SBR are tested ...
