...Prakash Chandra Gope; Harshit Kumar; Himanshu Purohit In this paper, crack growth tests on 19501 aluminum alloy friction stir welded butt joints after a single overload cycle in tension or in compression on compact tension (CT) specimens, along with constant amplitude tests, are investigated...

...Hongbin Zhang; Fujian Ni To describe the pavement load on the expressway, based on toll data, this paper analyzes the time and space distribution of the axle load spectrum for different vehicle types and different axle-wheel types. It studies the distribution of overload rate and overload weight...

...Anindito Purnowidodo; Shingo Fukuzato; Akihide Saimoto; Chobin Makabe The purpose of the present study is to evaluate fatigue crack propagation after tensile overloading. A 6-mm long u-shaped notch was cut in the center section of the specimen. Notch root radii of 0.1, 1, and 2 mm were chosen for ρ...

...C Makabe; A Purnowidodo; T Miyazaki; AJ McEvily In a previously reported study, it was found that the fatigue crack growth rate actually accelerated after a tensile overload under a negative value of baseline stress ratio R . This type of crack propagation behavior is related to the change...

...BB Verma; RK Pandey The present investigation studies the effect of a single tensile overload cycle on fatigue crack closure and its mechanism. Attempts have also been made to study the crack growth kinetics following the overload application. It is concluded that Stage I-type of crack propagation...

...Chobin Makabe; Anindito Purnowidodo; Toshiyasu Sueyoshi; Takao Utsunomiya In the present study, a detection method of an overload application during stress cycles under constant amplitude was investigated. Also, the effect of the tensile overload was shown at three stress ratios: R = 0, -1...

...C Makabe; H Kaneshiro; S Nishida; H Sakihama The fatigue crack propagation law was investigated for the two cases of crack propagation in a region of welding residual stress and after overloading. In the former case, the crack propagation rate d a /d N was found to depend on the stress ratio R...

...SK Putatunda; V Venugopal An investigation was carried out to examine the influence of overload plastic zone size on stress corrosion crack growth behavior for a low alloy steel. The investigation also examines the influence of initial stress intensity factor on stress corrosion crack growth...

...MA Pompetzki; TH Topper; DL DuQuesnay; MT Yu Intermittent compressive underload and tensile overload tests were carried out on smooth specimens to determine the effect of large stress cycles on the fatigue damage of subsequent small cycles. A load interaction damage model, using a power-law...
