The effect of straining mode on void growth

Large strain finite element method is employed to investigate the effect of straining mode on void growth. Axisymmetric cell model embedded with spher ical void is controlled by constant triaxiality: loading,while plane-stress model containing a circular void is loaded by constant ratio of straining. Elastic-plastic material is used for the matrix in both cases. It is concl uded that, besides the known effect of triaxiality, the straining mode whic h intensifies the plastic concentration around the void is also a void grow th stimulator. Experimental results are cited to justify the computation re sults.
