“…J-интеграл, предложенный Райсом в 1968 году [3,4,5], определяется как независимый от пути линейный интеграл, который характеризует напряжения и деформации наконечника трещины под действием упругих и / или эластопластических материалов. Согласно определению J-интеграла он является независимым от пути интегрирования и это свойство соблюдается при работе с модельными данными [6], однако в реальном эксперименте за счет ошибок в определении смещений, получаемых методом корреляции цифровых изображений, независимость от пути интегрирования не выполняется [7].…”

Estimation is to predict the outcome of seismic load to underground pipeline with manholes. Forces and shears were taken into account during modelling of seismic resistance. There were 3 types of waves identified in this job, and the estimation of the maximum velocity of the soil movement was made according to the category of soil by seismic properties. The seismic resistance was estimated under the action of both horizontal and vertical directions of seismic load. The model of a manhole was created from scratch by authors. The main supporting elements of the body were modelled in a stress-deformed mode. The transmission of seismic longitudinal P-waves was simulated with parameters up to 9 points inclusive at the MSK-64 scale in soils of medium density. Based on the analysis of the data obtained, a graph of maximum equivalent von Mises stresses was built depending on the phase of the seismic longitudinal P-wave transmission. Conclusions were made about the efficient usage of applying the proposed approach to solve this class of problems.
