摘要: ABSTRACT This paper discusses analytical and experimental results which show that plastic zone size in a precracked body with given aspect ratio, is mildly dependent on thickness decreases as the width increases. The import of these determination fracture toughness studies related to fatigue crack growth are discussed. A new procedure for size-independent proposed verified. problems relating reliable characterization size- geometry-independent rate briefly
