Two Modes and Criterion of Brittle Fracture

State Key Lab for Advanced Metal Materials, USTB, Beijing 100083, China

中文摘要

The plastic zone at the tip of the flaw (including acute cark and common notch) was investigated. For the notch specimen, a formula of toughness K_C^R was proposed, and its physical meaning was emphasized.Two modes of brittle fracture was identified and the evaluating criterion was established.
