Critical flaw size

Fracture mechanics was developed during World War I by English aeronautical engineer A. A. Griffith – thus the term Griffith crack – to explain the failure of brittle materials. Griffith's work was motivated by two contradictory facts: • The stress needed to fracture bulk glass is around 100 MPa (15,000 psi). • The theoretical stress needed for breaking atomic bonds of glass is approximately … WebOct 15, 2024 · We thus question the basis assumption of increasing critical flaw size with increasing specimen size associated to Weibull’s approach. Employing the CC to predict prematurate specimen failure initiating from a critical pore, we determine a relation between the failure force decrease and the corresponding possible critical pore size range ...

WebBecause of the conservative nature of ASIP, it is assumed that all critical airframe components have an initial flaw size to account for any damages that could have occurred during the manufacturing and maintenance processes. Generally, ASIP assumes a 0.05-inch flaw because it is equivalent to the minimum detectable flaw size of a typical ... WebFlaw sizes are important thresholds of crack length used to determine what is safe. To a structural engineer or materials scientist the critical flaw size is the length of the smallest crack in a structure that might cause immediate catastrophic failure.

WebThe critical flaw size in torsion is several times larger than the flaw critical size in tension. The damage maps in Figures 17–19 showed that at long lives it is much easier to nucleate cracks in torsion than in tension. As a result smaller flaws are not as damaging in torsion because other cracks will naturally nucleate in the material.
