摘要： In this paper, we proposed a new cr tenon or mixea-moae brittle fracture, i.e., the strain energy criterion, which can be stated as (KⅠ/KⅠc)2 +(KⅠ/KⅠc)2+(KⅡ/KⅡc)2=1. This criterion is shown to be in good agreement with known experimental data.In this paper, an experimental criterion:(KⅠ/KⅠc)m+(KⅡ/KⅡc)n=1, 1≤nm≤2.is also proposed.

关键词: unilateral contact, mathematical programming, quasi-active set
