What is Understanding Griffith about?
The Griffith Criterion explains how micro-cracks in brittle materials lead to localized stress and can cause brittle fracture when a crack propagates. It states that a crack will grow when the decrease in elastic energy equals the energy required to create new crack surfaces, with equations provided for stress required to propagate cracks in thin plates. The theory is applicable only to completely brittle materials, and modifications have been made to account for plastic deformation in crystalline materials
