• The fracture toughness must be evaluated under the dynamic loading condition, when the materials are used for structures tha are desired to a higher safety and must be taken into account of the effect of dynamic loading. Moreover, in order to obtain the valid <I>J</I><SUB>lc</SUB> value, a criterion concerning both specimen thickness <I>B </I>and ligament width <I>b</I><SUB>0</SUB> must be satisfied, which is called as "valid condition" and is described as the following equation.B, b0 ≥ α(Jin/σfs), (α=25)However, this equation is presented for the static loading condition and there is no assurance to be able the apply for the case of dynamic loading one. Therefore, under static and dynamic loading conditions, the effects of both <I>B </I>and <I>b</I><SUB>0</SUB> on <I>J</I><SUB>in</SUB> value and the flow stress σ<SUB>fs</SUB> are investigated and the valid conditions are discussed. The results are presented that the factor α of the above equation is reduced as 20 for <I>b</I><SUB>0</SUB> and is increased as 28 for <I>B</I> under dynamic loading condition.
