For regular hinge-rod structures, an engineering method for analyzing the stress-strain state is devel­oped, taking into account the transformation of the form by folding repeated fragments of the structure. For the software implementation of the proposed calculation algorithm, a macro is compiled in the APDL language, which is built into the ANSYS software package. A step-by-step procedure that simulates the transformation of the farm geometry was tested.

For regular hinge-rod systems, an engineering technique for analyzing the stress-strain state is developed, taking into account the transformation of the shape of the structure by folding repeated fragments in the plane of the smallest stiffness. As a result, the original straight shape turns into an arched truss. The proposed meth-od is based on the extension of the modified Lagrange method to the problem of analyzing the stress-strain state of a spatial truss structure with kinematically directed shape change. A step-by-step adjustment of the structure geometry is used, taking into account the resulting nodal displacements. For the software implemen-tation of the proposed calculation algorithm, a macro is compiled in the APDL language embedded in the ANSYS Mechanical software package. A step-by-step procedure was tested that simulates the transformation process of the spatial farm geometry.

Применение полимерных покрытий для ремонта корпусных конструкций выдвигает как актуальную задачу определения прочностных характеристик конструкций с покрытиями. Наличие отверстий, сквозной коррозии, являющихся концентраторами напряжений, делает эти места наиболее опасными, с точки зрения потери прочности, герметичности. Чаще всего разрушение происходит по адгезионному слою. Представлена математическая модель, учитывающая сосредоточенные усилия на концах адгезионного слоя композиционной конструкции типа «металл-покрытие». Проведены расчеты нормальных и касательных напряжений. Наибольшие значения напряжений в полимерном покрытии получены на кромке отверстия в слое металла. В результате анализа установлено, что увеличение перекрытия полимерным покрытием контура отверстия и удаленность от контура отверстия приводят к существенному уменьшению величин напряжений. Разработанная математическая модель и алгоритм вычислений позволяют расчетным путем определить напряженно-деформированное состояние металлической конструкции с отверстием и полимерным покрытием. The use of polymer coatings for the repair of hull structures puts forward as an urgent task to determine the strength characteristics of structures with coatings. The presence of holes, through corrosion, which are stress concentrators, makes these places the most dangerous, in terms of loss of strength, tightness. Most often, the destruction occurs along the adhesive layer. A mathematical model is presented that takes into account the concentrated forces at the ends of the adhesive layer of a composite structure of the "metal-coating" type. Calculations of normal and tangential stresses are performed. The highest stress values in the polymer coating are obtained at the edge of the hole in the metal layer. As a result of the analysis, it was found that an increase in the overlap of the polymer coating of the hole contour and the distance from the hole contour lead to a significant decrease in stress values. The developed mathematical model and calculation algorithm allow calculating the stress-strain state of a metal structure with a hole and a polymer coating.
