Abstract We address analytically and numerically
theproblemofcrackpathpredictioninthemodelsystem
of a crack propagating under thermal loading. We show
that one can explain the instability from a straight to a
wavy crack propagation by using only the principle of
localsymmetryandtheGriffithcriterion.Wethenargue
that the calculations of the stress intensity factors can be
combinedwiththestandardcrackpropagationcriteriato
