摘要: Both conservative line and area integrals are derived from the Betti reciprocal principle to determine stress intensity factor for a bimaterial strip. Numerical results presented demonstrate accuracy of methods. Several mesh types have been exploited examine effect meshing on results. Stress factors obtained by means integral vary somewhat between paths. Those found same value different
