The Summer School on Fracture Mechanics will be held on-line
The International Summer School on Fracture Mechanics can be useful for university students, Ph.D. students and young scientists, whose scientific interests are connected with mechanics.
The scientific programme of the school contains different areas of mechanics including material science, mechanics of solid deformable body and others.
The leading researchers will deliver lectures that deal with relevant problems of mechanical phenomena and present the results of latest studies in the respective areas.
The lectures will be held in the form of webinar, presentation, open discussion with the ability to ask questions in the real time using the Google Meet platform.
The registered participants of the school will get the link on their email address that allows to access the lectures, that were planned to de delivered during the summer school.
After the completion of summer school each participant will get the certificate with the signature.
The registration of summer school participants will be possible from June 14 to September 20.

Lecture title and abstract
Local approach to fracture for ductile failure
Models for ductile failure have been widely developed over the last decades reaching high sophistication. They are nowadays able to account for cavity growth while incorporating the effects of void shape and orientation, matrix anisotropy, coalescence by internal necking combining tension and shear. . . These models describe material softening up to failure. They can be used in Finite Element (FE) softwares to simulate failure of test specimens but also of actual industrial parts. The lecture will review the GTN model for ductile fracture and its numerous extensions. The use of this class of models in finite element codes will also be addressed. In particular numerical difficulties related to the strong softening character of the models will be studied. Numerical solutions using material internal lengths (so called “non local” models) will be described. Applications to large size structures will be presented.

Fatigue crack propagation: experimental procedures and results analysis
The experimental procedures to perform the fatigue crack propagation tests are reviewed in the light of the fracture mechanics principles and of the ASTM standard, considering both the threshold conditions and the fatigue crack propagation of long cracks. The main fatigue crack propagation mechanisms are also reviewed considering different alloys. Finally, the analysis of the fatigue crack propagation results is discussed, mainly focusing their statistical dispersion, also considering the influence of the alloys microstructures.

Fatigue tests on bending and torsional loads at non-standard test stand
Standard machines for fatigue tests are usually constructed to determine the basic fatigue characteristics of materials for tension-compression or torsional loading. Due to the complexity of processes occurring in materials during fatigue under load conditions other than those mentioned, a series of other tests are performed to determine the effect of e.g. stress gradients or strains. This requires the extension of the equipment of standard laboratory machines or the construction of specialized, dedicated fatigue stands.
This presenation describes the method of operation and load control in research stands designed, constructed, produced and used in the Opole University of Technology for fatigue tests under cyclic bending, torsion, and a proportional combination of cyclic bending and torsion. All presented stands base on the same structure, however different drive systems allow performing tests with controlled amplitudes of load or strain. The stands described in the paper are characterized by a simple structure based on the inertial method of generating the working load. Due to the small dimensions of the samples tested, the stand drive is equipped with an electric motor and a simple to use control system. The drive with control and measuring system require a small power supply about 1,5 kW.

Hydrogen Induced Damage in Structural Steels
The lecture outlines metal degradation mechanisms and the challenges related to hydrogen induced damage in structural steels. Current understanding of the effect of hydrogen on fracture and mechanical properties of steels will be presented. Focus will be given on the influence of long-term operation of steels on their susceptibility to hydrogen induced damage. Microstructural, mechanical and electrochemical indicators of hydrogen induced damage of structural steels will be considered. Proposed in-laboratory methods of accelerated hydrogen assisted steel degradation will be described. The methods for evaluating the hydrogen induced degradation of steels will be highlighted. The durability and integrity issues in existing natural gas pipelines associated with hydrogen embrittlement of steel at transporting hydrogen or mixtures natural gas with hydrogen will be outlined.
