Development of Strength and Yield Criteria Based on the Relationship Between Elastic and Plastic Strains.

The presented research results imply a certain relationship between elastic and plastic parts of strain. Based on the preliminary summary of this relationship, a new strength criterion is proposed, which can be treated as modification of the maximum principal strain criterion. Since the proposed approach establishes a relationship between strength and yield criteria, it can also be treated as a new yield criterion. [ABSTRACT FROM AUTHOR]
