    Based on Well's δ theory, an idea of equivalent rotational factor req, used to calculate COD, is put forward. The equivalent rotational factor req is different from the commonly used rotational factor r, and the general expression, of req has been derived as follows.In fact , the equivalent rotational factor req depends on the mechanical properties of metals as well as the degree of deformation . The experiments show that the values of req, for steels and non-ferrous alloys are quite different.A suggestion is offered here that really a single P-V curve is sufficient to measure all the values of K1c, δc and J1c, it brings out the simplicity of experimental procedures. Formula for J calculation by means of the area under P-V curve has been derived as follows:where p is a function of req, orwhere β is a function of the rotational factor of plastic component.Comparing the results of J calculated from P-V curve with that fhom P-△ curve, it is found that there is only a little difference between the two.The correlation between J and COD has been studied with respect to seven different materials. Measuring results give a better understanding of the confessed equation J = Mσsδ and convincingly indicate that the value of M relates to the properties of materials and varies from 1 to 2(cf. table 6 and 7). NomenclatureVg-mouth opening displacement ;r1-rotational factor after yielding ;σs-yield stress;W-width of specimen ;αf-final crack length ;z-thickness of knife edge ;α-initial crack length ;B-thickness of specimen ;rp-rotational factor of plastic component ; Ge-elastic component of J ;UV-area under P-V curve ;UVP-plastic component of area under P-V curve ;p-load;Csys-compliance of loading system ;E-modulus of elasticity ; v-Poisson's ratio;γ-a function of a/W[cf.eq.(1)].

    以Wells的δ理论为基础,提出用等效req计算δ的意见。导出了req的一般表达式。同时指出材料不同、材料的变形程度不同,req不同。般提出只用一条P-V曲线来计算K_(1c)、δ_c或J_1。推证了由P-V曲线计算J下积分的公式。并对公式进行了讨论。文中最后对J与δ的关系进行了实验研究。
