BEHAVIOR OF FINITE 2-PHASE BODIES IN RESPONSE TO INTERNAL AND EXTERNAL STRESSES .2. NUMERICAL CONSIDERATIONS

A discrete dislocation method in conjunction with a surface dislocation analysis has been applied to a two-phase body subjected to either an internal stress or an external stress. The analysis can be performed by assuming either that all surface dislocations belong to the two-phase system or that each of the surface arrays belongs to a single phase in which it is located. It has been shown that these two methods are equivalent. The results of the discrete dislocation method are in complete agreement with the method of continuous distribution of dislocations. The geometry of the two-phase body subjected to an internal or external stress illustrated in Part I of the present study has thus been verified. It has been shown that the discrete dislocation method can be employed with relative simplicity when applied to complex geometries associated with a finite two-phase body. © 1979.
