Special Issue Information

Dear Colleagues,

This Special Issue (SI) covers a wide range of modern achievements in the study of the behavior of solids with cracks—from studies of cyclic durability and the nucleation and growth of a fatigue crack to solving a number of complex problems of fracture mechanics. In this SI, limiting and prelimiting equilibrium states of materials and structures under single, multiple, thermal, and dynamic loading in elastic, viscoelastic, and elastoplastic bodies with cracks will be considered. We also invite you to submit articles on new criteria for crack resistance of materials for structural integrity.

Considerable attention will be paid to the application of numerical methods for the analysis of stresses and strains in solids and constructions with notches and cracks. We will also be glad to see the results of studies on predicting the operability of structures according to the test data of laboratory samples, taking into account the scale factor based on similarity criteria for local fractures.

Considerable attention will be paid to research methods and the basic laws of fatigue and cyclic crack resistance of metals and alloys in deterministic and probabilistic settings. Also relevant for consideration are the characteristics of high cyclic fatigue for materials manufactured by new technological methods. We invite articles devoted to the basic laws of cyclic plasticity and fatigue of metals and alloys (especially those produced by additive manufacturing).

We also invite papers devoted to the deformation and energy criteria of fatigue fracture of metals estimation by FEM and experimental verification. Particular attention will be paid to the development of methods for accelerated determination of endurance limits based on deformation and energy criteria. The problem of predicting the development of cracks and probabilistic fatigue modeling will also be discussed.

This work investigates fracture characteristics of a marble semi-circular bend (SCB) specimen with a pre-defined crack under a compressive loading condition. It aims at evaluating how the fracture toughness can be affected by the crack and span length variation. Numerically, the model is solved using meshless methods, extended to the linear elastic fracture mechanics (LEFM), resorting to radial point interpolation method (RPIM) and its natural neighbor versions (NNRPIMv1 and NNRPIMv2). Alternatively, to validate the meshless method results, the problem is resolved following the finite element method (FEM) model based on the standard 2D constant strain triangle elements. As a result, fracture toughness and the critical strain energy release rate are characterized following the testing method on the cracked straight through semi-circular bend specimen (CSTSCB). A comparison is drawn amongst the theoretical, meshless methods and FEM results to evaluate the capability of advanced numerical methods. Encouraging results have been accomplished leading to validate the supporting numerical methodologies. Full article

To study the effect of strength, stiffness and inclination angle of square inclusions on failure characteristics of rock, uniaxial compression tests were carried out on prismatic sandstone containing a square hole with different filling modes and hole angles using a servo-hydraulic loading system. Digital image correlation and acoustic emission techniques were jointly applied to analyze the damage and fracture process, and the crack stress thresholds were determined qualitatively and quantitatively by combining the stress–strain behavior. The results show that the mechanical properties and crack stress thresholds of pre-holed specimens increase with the increase of the strength and stiffness of inclusions, and are affected by the hole angle. Rock failure is mainly caused by secondary crack propagation and shear crack coalescence, eventually forming mixed tensile-shear failure. The crack behavior, especially the crack initiation position, is affected by the filling mode and the hole angle. Interface debonding tends to initiate at the vertical interface, while interface slipping tends to propagate along the inclined interface. Under identical loading conditions, the specimen with 45° hole is more susceptible to crack and damage than that with 0° hole. Notably, inclusions can inhibit the hole deformation and the fracture of rock matrix, especially the sidewall spalling of 0° hole. Full article
