Introduction The theory of elastic fracture originated by AA Griffith’s in 1921 (Griffith 1921) is well known, and although Griffith’s used the “theorem of minimum potential energy” (his italics) the manner in which he used this theorem seems to have obscured its more

Web• Irwin and Orowan suggested Griffith’s equation can be applied to brittle materials undergone plastic deformation before fracture by including the plastic work, γp, into the total elastic surface energy required to extend the crack wall, giving the modified Griffith’s equation as follows : WebDec 1, 2024 · The year 2024 marks the 100th anniversary of Griffith’s Fracture Theory. Many scholars regard Griffith as the father of the linear elastic fracture mechanics. Here, Nicola Pugno—who received the Griffith Medal and Prize in 2024—reflects on some Griffith’s based approaches and quantized-related extensions of the original theory, as …
WebGriffith theory of brittle fracture initiation and its modifications have been discussed in hundreds of technical papers. A particularly useful review was presented by Fairhurst (1972) which is recommended reading for anyone interested in pursuing this topic in greater depth.
