Crazing mechanism based on plastic instability

Abstract

The mechanism of the nucleation of craze from the region of pre-formed voids is discussed on the basis of the finite elements analysis for an elastic plastic material containing a twodimensional array of cylindrical voids. Calculations are made for the two kinds of boundary conditions with respect to the constraint of the transverse strain under simple tension. The craze formation is considered to be an unstable concentration of plastic strain within the ligament between neighbouring voids. The present calculation shows that the constraint of the transverse strain is the essential factor in craze formation.
