Metal structural elements remain the primary construction material in many modern structures, which are subject to stringent requirements for safe and reliable operation. During service, structural elements undergo deformation and are exposed to various physical fields and environmental conditions. Situations involving two or more concurrent degradation factors pose particular risks. This study presents selected results of experimental and theoretical studies on the influence of an electromagnetic field and the orientation of its field lines on the corrosion wear of thin-walled steel elements. It also examines the effect of a magnetic field on the corrosion behavior of deformed thin-walled samples. The experiments were conducted in both urban and rural environments. The samples were exposed to the test environment for a specified period. Deformation was introduced using different methods.An experimental - theoretical approach was employed to evaluate the degree of corrosion wear and to determine the mechanical properties of the samples. Tangential and bending stiffness were calculated using relationships derived for the case of pure bending. The results indicate that corrosion wear is greater in samples not subjected to a magnetic field than in those exposed to magnetic field effects. Samples with surfaces oriented parallel to the Earth’s magnetic field lines exhibit more pronounced corrosion. It was also found that the tangential stiffness of undeformed samples under magnetic field exposure is slightly higher than that of tensile-deformed samples, whereas the bending samples of tensile-deformed samples exceeds that of undeformed ones. The study reveals new effects of both theoretical and practical significance.

Металлические элементы конструкций продолжают оставаться основным конструкционным материалом многих современных конструкций, к которым предъявляются высокие требования по обеспечению безаварийной и безотказной работы. В процессе эксплуатации элементы конструкций деформируются и находятся под воздействием физических полей и сред. Особую опасность представляют случаи, когда имеют место два и более источника разрушения. В работе приведены некоторые результаты экспериментально-теоретических исследований влияния электромагнитного поля и направление его силовых линий на коррозионный износ стальных тонкостенных элементов, а также влияние магнитного поля на коррозию деформированных тонкостенных образцов. Эксперименты выполнялись в городских условиях и за пределами города. Образцы выдерживаются в исследуемой среде в течение заданного времени. Деформации образцов создавались различными подходами. Для оценки степени коррозионного износа и определения механических свойств образцов используется экспериментально-теоретический подход. Для вычисления тангенциальных и изгибных жесткостей образцов используются соотношения для случая среднего изгиба. Установлено, что коррозионный износ образцов без воздействия магнитного поля выше, чем образцов, находившихся под воздействием магнитного поля. Большей коррозии подвержены образцы, поверхности которых параллельны силовым линиям магнитного поля Земли. Установлено также, что тангенциальная жесткость недеформированных образцов под воздействием магнитного поля несколько выше соответствующих жесткостей растянутых образцов, при этом изгибная жесткость растянутых образцов больше изгибных жесткостей недеформированных образцов. Обнаружены новые эффекты, имеющие важное теоретическое и практическое значение.
