A classical analysis of Irwin and Corten relates the minimum pressure to sustain crack propagation along a pipeline to the dimensions, elastic modulus and fracture resistance of the pipe wall. Although the model is inapplicable to gas pressurisation, it is here modified to become sufficiently accura

โฆ Synopsis
In this paper the crack-growth resistance of wood is discussed on the basis of an energy consideration, The 'Nc-constant load-displacement curve' method has been used to obtain the crack-growth resistance curves for two different orientations of mode I fracture. These fracture resistance curves give a more relevant and exact result on the crack propagation in wood than LEFM's parameters like I(ic.
