Study on Simulation of Cyclic Plastic Behavior of Ship Structural Pollycrystalline Metallic Materials under Cyclic-Loading Conditions (6th Report) -Calculation of Cyclic Slip Deformation Behaviour based on the Micromechanical Dislocation Model-

摘要

The propriety of the approximate calculation method for cyclic deformation behavior analysis proposed by Reppeto-Ortiz [Acta mater. 45, 6(1997) 2577-2595] based on the constitutive model developed by Ortiz-Popov [Proc. R.Soc. Long. A 379 (1982) 439-458] which emanates directly from a clear micromechanical picture is examined. It is needed to establish such calculation method in order to deepen our understanding of micromechanical aspects of PSBs formation process.
