Using classical techniques of complex analysis, the assumption of stable growth is expressed in terms of the parameters defining the elastic field around the tip. We explore the consequences of the local condition obtained and analyse its role as a crack propagation law. In particular, we herein extend to bounded domains a number of results previously obtained for the whole plane.engjournal articlehttp://www.springerlink.com/content/0376-9429/open access539.2Anti-symmetry principleQuasistatic crack growthLinear elasticityBrittle materialAnti-plane fieldsConfigurational forcesCrack propagation lawFísica de materiales
