Special Issue Information

Dear Colleagues,

Fracture mechanics is a crucial tool for understanding the failure mechanisms of materials and structures, particularly in high-stress or critical applications. This Special Issue aims to provide an in-depth exploration of the latest developments in the application of fracture mechanics to structural engineering. By showcasing cutting-edge research and case studies, the issue will explore how fracture mechanics can be employed to enhance the design, maintenance, and safety of various types of structures. Topics will include both theoretical and practical aspects of fracture behavior, with a focus on advancements in analytical methods, experimental techniques, and real-world applications.

Topics of interest include, but are not limited to the following:

  • Fracture toughness and fatigue crack growth in materials;
  • Structural integrity assessment and reliability using fracture mechanics;
  • Advanced numerical methods in fracture mechanics analysis;
  • Experimental techniques for fracture analysis in structures;
  • Case studies of fracture mechanics applications in civil, mechanical, and aerospace engineering;
  • Failure analysis and damage prediction in structural components;
  • Influence of environmental factors (e.g., temperature and corrosion) on fracture behavior;
  • Application of fracture mechanics in design codes and standards.

This paper assesses experimentally and theoretically the hydrogen-assisted cracking sensitivity of an ultrahigh-strength lath martensitic steel, recently used to manufacture tendon rods for structural engineering. The experimental values of the J-integral were obtained by tensile testing up to failure precracked SENT specimens in air, as an inert environment and in a thiocyanate aqueous solution, as a hydrogen-promoter medium. In parallel, the theoretical resources necessary to apply the Dugdale cohesive model to the SENT specimen were developed from the Green function in order to predict the J-integral dependency on the applied load and the crack size, with the cohesive resistance being the only material constant concerning fracture. The comparison of theoretical and experimental results strongly supports the premise that the cohesive crack accurately models the effect of the mechanisms by which the examined steel opposes crack propagation, both when in hydrogen-free and -embrittled conditions. The identification of experimental and theoretical limit values respectively involving a post-small-scale-yielding regime and unstable extension of the cohesive zone allowed for the value of the cohesive resistance to be determined, its condition as a material constant in hydrogen-free medium confirmed, and its strong decrease with hydrogen exposure revealed.
