... Fracture Notch Volumetric method Stress intensity factor Toughness For brittle mode, I fracture in a mainly elastic regime; current fracture assessment methodology relies on plane strain fracture toughness, K_IC, which is assumed to be a material property (Williams, 1957 ; Rice, 1974...

...Muhamad Husnain Mohd Noh; Mohd Akramin Mohd Romlay; Chuan Zun Liang; Mohd Shamil Shaari; Akiyuki Takahashi Purpose Failure of the materials occurs once the stress intensity factor (SIF) overtakes the material fracture toughness. At this level, the crack will grow rapidly resulting in unstable...

... repair solution. Design/methodology/approach The patch hybridization is performed by preparing the hybrid composite from tows of carbon fiber and glass fiber. Rule of hybrid mixture and modified Halpin–Tsai’s equation are used to evaluate the elastic constant. The stress intensity factor...

...Hamid Hamli Benzahar Purpose The purpose of this paper is to evaluate theoretically and numerically the stress and stress intensity factor (SIF) at the time of propagation of the crack in bi-material. The problem is formulated using two thin materials which are bound by a cracked adhesive...

... the numerical results and the analytical solution proposed for pure Mode II testing. Design/methodology/approach – The work presented in this note is experimental. The proposed methodology is of an hybrid experimental/numerical nature in that a numerical stress intensity factor calculation hinges upon...

... and subcritical crack increments caused by loads at high stress intensity factors. An effect of overloading peaks with a maximum that exceeds J_Q should be assessed using a special analysis beyond the scope of the FASTRAN retardation model. Originality/value – Measurements...

...Mario Guagliano; Kazuhiro Oda; Xin Lan; Nao‐Aki Noda; Kengo Michinaka Purpose The purpose of this paper is to compute the stress intensity factors (SIFs) of single edge interface crack for arbitrary material combinations and various relative crack lengths, and compare with those for the bonded...

... pipe structure. The stress intensity factor was considered as a parameter controlling the fracture behavior. The semi‐elliptical shape of the crack front was estimated under assumption of constant stress intensity factor along the crack front. Findings According to the results obtained in the paper...
