... pipeline burst capacity defect interaction longitudinal compression FEA Metal-loss corrosion threatens the structural integrity of oil and gas pipelines as it causes thinning of the pipe wall and therefore reduces the pressure containment capacity, i.e., burst capacity, of the pipeline...

... capacity of the pipeline under internal pressure only, which is developed in a recently completed study, multiplied by a correction factor to account for the effect of the longitudinal compression. Extensive parametric elastoplastic finite element analyses (FEA) are carried out, the results of which...

... 2019 ductile fracture fracture strain X65 grade steel notched round bar grooved plate FEA The experimentally obtained stress–strain relation is only valid up to the ultimate stress where the diffuse necking (localized plastic strain) reduces the cross-sectional area and the observed...

...-dimensional (3D) finite element analyses (FEAs). Two-dimensional FEAs are first carried out to verify the reported accuracy and applicable ranges for each equation based on the plane strain models with six different crack lengths. Three-dimensional FEAs are then carried out to estimate the errors...

... element analysis. The results show that the current practice needs to be revised or rejustified in an alternative manner. API 650 steel storage tank elevated temperature tank low cycle fatigue peak alternating stress FEA In the petroleum process industry, above ground steel storage...

... pipes due to seismic landslide. buried polyethylene pipe seismic landslide constitutive model failure criterion curve FEA As the main transportation tool for oil and natural gas, pipelines play a great role in the development and stability of the national economy. Compared with steel...

... stresses FEA In many industries, storage tanks are needed to hold liquids like asphalt, residuum, high pour point hydrocarbons, etc., at higher temperature than the ambient. This gives rise to thermal stresses in the tank, especially near the shell-to-bottom joint. The magnitude of thermal stress...

... difference between the end of the proportional limit of the material and the 0.5% yield point. For example, the end of the proportional limit is 250 MPa for the transverse direction, while the 0.5% yield point is 425 MPa. For the FEA plastic models of metals, the proportional limit and yield point...

... with full ranges. The utilization of numerical finite element analysis has been widely used to extend the full-scale test limitations. However, it is still impossible to run finite element analysis (FEA) for all possible combination of input parameters of geometry, material, and operating conditions. One...

... from the FEA. From Table 8 , one can find the burst time ( t b ) . Or, from practical standpoint, one can choose the pulse duration of the spike as t b since these two numbers are close. The static ultimate strength of A-106B steel is 60,000 psi. Thus, 4 ε ̂ = 0.262...

... the ultimate dynamic strength of low carbon steel is developed. Based on the agreement between the results of the finite element analyses and those of the empirical formula, it can be concluded that a properly modeled finite element analysis (FEA) can be employed with sufficient accuracy to study the short...
