The well-known fatigue crack growth (FCG) curves are two-parameter dependents. The range of the stress intensity factor ?K and the load ratio R are the parameters normally used for describing these curves. For engineering purposes, the mathematical representation of these curves should be integrated between the initial and final crack sizes in order to obtain the safety factors for stresses and life. First of all, it is necessary to reduce the dependence of the FCG curves to only one parameter. ?K is almost always selected and, in these conditions, considered as the crack driving force. Using experimental data from literature, the present paper shows how to perform multiple regression analyses using the traditional Walker approach and the more recent unified approach. The correlations so obtained are graphically analyzed in three dimensions. Numerical examples of crack growth analysis for cracks growing under nominal stresses of constant amplitude in smooth and notched geometries are performed, assuming an identical material component as that of the available experimental data. The resulting curves of crack size versus number of cycles (a vs. N) are then compared. The two models give approximately the same (a vs. N) curves in both geometries. Differences between the behaviors of the (avs. N) curves in smooth and notched geometries are highlighted, and the reasons for these particular behaviors are discussed.

把描绘发达国家经济增长过程中的环境负荷曲线比喻成“环境高山”。强调了发展中国家,尤其是中国,发展经济的正确之路是:从“环境高山”的半山腰穿过去,走新型工业化道路。推导了环境负荷与GDP之间的关系式,其中GDP年增长率g和单位GDP环境负荷年下降率t是两个关键变量。以一些国家和中国的一些省份为实例,分析了经济增长与能源消费量之间的关系。在不同的假设条件下,计算了2005,2010,2020年中国的环境负荷,并以能源消耗为例,做了进一步的说明。
