“…The study [17] presented a mixed variation formulation of static and dynamic problems for thin-walled beams, as well as a comparison of the numerical results of mixed and classical finite element methods. In [18], the finiteelement method was used to study the behavior of crack propagation in a sandwich-foam plate and to obtain the corresponding crack growth paths from the criterion of fracture mechanics.…”

The distribution of the main stresses in the section of the ceramsite concrete fixed formwork block with four cells

One of the main issues in block design is the prediction of possible areas of crack formation and their further spread. In structural elements, one of the possible places of crack formation is stress concentrators, because, under an external load, significant local stresses arise in the cross-sections of such parts, which can lead to their destruction. This article discusses possible ways to refine the section to reduce the stress concentration in places of a sharp change in the section of the block. After modeling the distribution of the main stresses in the section in the Abaqus program, it was revealed that with a radius of rounding at the inner corners of the block cells, the maximum values of the main tensile stresses decrease significantly, as does their distribution zone. At the same time, the maximum values of the main compressive stresses increase slightly, and their distribution area increases significantly.
