Special Issue Information

Dear Colleagues,

Fatigue and fracture are the main forms of structural failure in service. According to relevant data, the annual losses caused by fatigue and fracture are equivalent to about 4% of the total national economic output value. Therefore, countries around the world attach great importance to the study of fatigue and fracture mechanisms and their preventive measures. The research and application of fatigue and fracture involve important industries and key fields such as aerospace, transportation, building materials, metallurgy and minerals, petrochemicals, and transportation. The science and technology of fatigue and fracture in various materials and structures have undergone intense development over the last several decades; nevertheless, this field is still in a phase of progression.

The main goal of the Special Issue on “Fatigue Damage, Fracture Mechanics of Structures and Materials” is to address the safety evaluation and life prediction issues of materials and structures, promote theoretical research and technological applications in the field of fatigue and fracture around the world, serve economic construction and social development, and strengthen exchanges, discussions, and cooperation among experts and scholars in this field. Original contributions on the design, research and development studies, experimental investigations, theoretical analysis, and computational methods relevant to the fatigue and fracture of materials and structures are welcome. Topics of interest include (but are not limited to) the following:

  • Experiments of advanced materials and structures;
  • Fatigue and fracture mechanics;
  • Microscopic mechanisms of fatigue and fracture in advanced materials and structures;
  • Research on the failure theory of typical materials and structures;
  • Numerical simulations of fatigue and fracture in advanced materials and structures;
  • Lifecycle damage failure and life prediction of structures;
  • Fatigue and fracture engineering applications in key industries;
  • Design and application of advanced materials and structures for fatigue prevention and control;
  • New advances and technologies in the field of fatigue and fracture;
  • Multiscale modeling of advanced composite materials and structures;

The Ti-6Al-4V alloy is a typical α + β type titanium alloy and is widely used in the manufacture of aero-engine fans, compressor discs and blades. The working life of modern aero-engine components is usually required to reach more than 108 cycles, which makes the infinite life design based on the traditional fatigue limit unsafe. In this study, through symmetrical loading high-cycle fatigue tests on Ti-6Al-4V titanium alloy, a nonlinear cumulative damage life prediction model was established. Further very-high-cycle fatigue tests of titanium alloys were carried out. The variation law of plastic strain energy in the evolution process of very-high-cycle fatigue damage of titanium alloy materials was described by introducing the internal stress parameter. A prediction model for the very-high-cycle fatigue life of titanium alloys was established, and the sensitivity analysis of model parameters was carried out. The results show that the established high-cycle/very-high-cycle fatigue models can fit the test data well. Moreover, based on the optimized model parameters through sensitivity analysis, the average error of the prediction results has decreased from 59% to 38%. The research aims to provide a model or method for predicting the engineering life of titanium alloys in the high-cycle/very-high-cycle range. Full article
