“…The connecting rod must be able to withstand enormous loads and transfer large amounts of power smoothly. According to Lee et al [19], failure usually occurs at the big end of the connecting rod. The stress distribution was estimated and the value of the corner radius was optimized by using ANSYS software.…”

“…A FE study of the con-rod shank and, especially, of the transition zone between small end and shank is reported in [1,13] and a numerical analysis of the influence of fillets adopted in this area is presented in [14]. In [15,16] an optimization of the transition geometry between the shank and the big end is addressed. In [17,18] various shank failures at different positions are reported.…”

“…Also, HAZ was found to have the lowest toughness in welded joints (9). According to another report, this softened region observed in HAZ is caused by the tempering effect imposed by the heat generated during welding [10]. Therefore, the purpose of present work is set to analyze the effect of microstructure change caused by weld on the fatigue crack propagation velocity in low ∆K range.…”

There exists strong environmental and economic pressure to increase the thermal efficiency of fossil fuel power stations and this has led to a steady increase in operating temperature and pressure resulting in the world wide construction plans for ultra super-critical power plants. Consequently, in order to improve the thermal efficiency of power plant, there has been a strong drive to develop more advanced heat resistant steels with excellent creep, high temperature fatigue and thermal fatigue resistant properties as well as superior oxidation and corrosion resistant properties. In this study, the test material was P122 alloy which was developed for ultra super-critical power plant. To measure the fatigue crack growth rate in low #K range, fatigue tests were performed on the P122 alloy welds by #K decreasing method at three different microstructure (Base metal, HAZ, Weld metal) regions. Microstructure observation and micro-hardness tests performed for all three regions to find the relationship among the crack growth rate, microstructure and hardness. Fatigue tests were performed with compact tension specimens at 600°C, 650°C and 700°C at the loading frequency of 20Hz.
