Abstract
. This article considers a double periodic cage with round plane holes filled with unstressed washers made of an isotropic elastic material, the surface of which is uniformly covered with a homogeneous film. Each fiber and medium (binder) is stretched by two biperiodic linear cracks. Each washer has a centrally located crack, the length of which is less than the diameter of the washer. The introduced stresses and their displacements are expressed by an analytical function. In the process of solving the problem, boundary conditions are set along the contour of round holes, as well as along straight cracks. Thus, on the basis of the boundary conditions, a system of linear algebraic equations is obtained. Their solution is solved by the Gauss method. In the latter case, the stress intensity factor at the crack tips is determined.
期刊介绍：
Engineering Transactions (formerly Rozprawy Inżynierskie) is a refereed international journal founded in 1952. The journal promotes research and practice in engineering science and provides a forum for interdisciplinary publications combining mechanics with: Material science, Mechatronics, Biomechanics and Biotechnologies, Environmental science, Photonics, Information technologies, Other engineering applications. The journal publishes original papers covering a broad area of research activities including: experimental and hybrid techniques, analytical and numerical approaches. Review articles and special issues are also welcome. Following long tradition, all articles are peer reviewed and our expert referees ensure that the papers accepted for publication comply with high scientific standards. Engineering Transactions is a quarterly journal intended to be interesting and useful for the researchers and practitioners in academic and industrial communities.
