利用混凝土裂纹尖端附近等εθ线，建立了ⅠⅡ复合型裂纹断裂等εθ线形状应变能准则，并与其他理论预测值以及试验数据进行对比分析.结果表明：该准则的预测结果与试验数据基本吻合.
Using the iso εθ line of concrete crack tip, the shape strain energy criterion of iso εθ line forⅠ Ⅱmixed mode crack was established by comparing with the predicted value in other theories and known experimental data.The results show that predicted value of this criterion is in agreement with known experimental data.
