摘要
1.Introduction A minor structural defect in engineering materials can intro-duce considerable local stress concentration,potentially leading to catastrophic failure that would result in significant loss of life and properties^([1-4]).Therefore,effective mitigation of local stress con-centration is an important task in materials design.In the compo-sition design and metallurgical production process of metallic ma-terials,inclusions or secondary phases that have significant differ-ences in elastic modulus from the matrix are often formed^([5,6]).
