Study of FEM Simulation of Cyclic Plastic Behavior of Face-Centered Cubic Crystal (F.C.C.) Crystalline Materials: 4th Report

摘要

A crystalline FEM theory is applied to investigate the relationship of the crystal geometry to the progress of plastic deformation localization )P.D.L.) and irreversible slip generation (I.S.G.), which are part of the fatigue crack initiation process, by calculating the cy6clic deformation behavior of a FEM model of a f.c.c. crystal which reproduces the restriction caused by the neighboring grains.
