Outline of Final Research Achievements	A fundamental study for a strip yield modeling based on an equivalent distributed stress is carried out. The fracture mechanics theory is formulated and discretized using a program. The numerical results are compared with those of finite element results and brittle fracture testing guidelines. Relation between classical criteria and presented approach are investigated. The proposed approach is adopted two-dimensional edge crack problem and three-dimensional surface crack problems. The results are examined.
