Information × Registration Number 0207U002339, 0104U006428 , R & D reports Title Development of optimization procedures for exploitation parameters of oil pipelines to guarantee their given resource with allowance for pipe’s defects and effect of environment popup.stage_title Head Kushnir R.M., Registration Date 24-01-2007 Organization Pidstryhach Institute for Applied Problems of Mechanics and Mathematics NASU popup.description2 A mathematical model for definition the subcritical growth of corrosion-fatigue cracks in metallic bodies is formulated. The method of equivalent areas for definition the period of subcritical growth of fatigue plane cracks in homogeneous elastic field of 3D bodies is developed. A mathematical model of loading the pipe of buried oil pipeline relative to the real exploitation conditions is proposed. The model takes into account the pipeline’s longitudinal tension-compression under its fastening and bifrequency cyclic loading by pressure. The analysis of dependence of residual durability of the pipe of oil pipeline on its exploitation parameters is made Product Description popup.authors popup.nrat_date 2020-04-02 Close
