Abstract: When a crack is running, the temperature rise is a quite important actual problem, which not only depends on some material constants, but also the propagation velocity and the distribution of the heat resource density. In this paper, the shape of plastic zone around the crack tip and the density of heat resource have been discussed and the model of the temperature fields has been proposed. The numerical results with PMMA are given and comparedwith other theories and experimental results.

Key words: stenosis, degree of anisotropy, trapping bolus, free tube, tethered tube
