Abstract The size of the plastic enclave at the tip of a crack within an externally loaded elastic medium is important for the complete understanding of the stress distribution in the cracked medium. One of the first useful approximations of zone size was given by Irwin[1]. Later, Dugdale[2] significantly aided in the estimation of plastic enclave lengths by introducing his elastic-plastic strip model of the enclave region. Experimental results from tests made by him and others [3] with mild… CONTINUE READING
