“…For the periodicity cell in question, six types of experiments have been realized: stretching along the X, Y, Z axes in order to determine the effective Young's moduli and Poisson's ratios and the net shift in the planes XY, XZ, YZ to determine the shear moduli. Effective modules were obtained by volume averaging [11] using the following dependencies:…”

Within the framework of the present work, the results of calculation and experimental studies of the mechanical characteristics of textile composites with a thermoplastic matrix are presented. A software module and a numerical model for calculating the effective elastic characteristics of composite materials with a thermoplastic matrix are developed. At the heart of the developed software module implemented in the engineering package ANSYS, the method of averaging by volume, integrated into ANSYS Mechanical, is applied. Based on the results of numerical experiments, effective elastic characteristics for a periodicity cell with an interlacing of 5H Satin and a layered composite material were determined. The verification of the developed numerical models has been carried out.

A numerical and experimental study of the regularities of the influence of the most likely defects such as local bundles inside multilayer cylindrical large-sized housings on the deformation and strength characteristics of the housings near their end connection is carried out. A statistical analysis of discontinuities in the manufacture of holes for pin-pin connection at the front and rear junctions of the joint is carried out. To form a sample, the results of accompanying passports of more than 200 build-ings were processed. Based on the results of ultrasonic flaw detection, the areas of discontinuities at the front and rear junctions of the joint were determined, and as a result of statistical processing, diagrams of the distribution of discontinuities were con-structed. Physical models of cases in the form of multilayered cylindrical rings with the presence of probable defects in the structure such as local bundles are made and, further, to conduct ring tests according to the standard method to study the effect of local bundles on the deformation and strength characteristics of the ring. The relationship between the relative strength limit and the coefficient of discontinuity (delamination) of the composite structure of the ring is established using the obtained exper-imental data. A defect in the form of a bundle, on the one hand, leads to a decrease in the mechanical characteristics of the ma-terial, and on the other hand, leads to a concentration of stresses in the bundle zone. The total effect of stratification is ex-pressed in an increase in the corresponding stresses that characterize the state of the loaded structure, and, accordingly, a de-crease in its load-bearing capacity. A mathematical model is developed and numerical modeling is performed on its basis.
