Considered the effect of initial ovality, the method of theoretical analysis and numerical simulation are adopted by Gong (2019) to study the local buckling of single-layer pipeline and double-layer pipeline, and a calculation method of collapse pressure...

... and concrete material model *MAT_078, the residual strength after cracking is defined by strength reduction factor which is written in the Eq. (2): f 1 f p (1 B) f r (2) where is the failure strain at which cracking starts, is the plastic strain at which residual strength is reached and B...

..., the ultimate bearing capacity of the ground is estimated by finite element analysis. The failure mode of Terzaghi's bearing capacity theory is related to the residual strength of soft rock. The effect of the ratio of peak strength to residual strength on the ultimate bearing capacity of soft rock is clarified...

... sand sample, the initial shear stiffness and peak strength of the hydrate sample increased significantly with the increase of the shear rate, but it was not observed that the residual strength was affected by the shear rate. The volume strain of hydrate samples gradually changes from shear compression...

.... Finally, specific model to correlate the pipe residual strength to the damage dimensions was developed too. The innovation of the proposed approach is the capability to re-create cracks on pipelines realistically damaged and operated. Results and methodology are of interest for operation and maintenance...

... Abstract While the offshore pipelines are designed to withstand an extensive range of combined loads such as the internal/external pressure, axial force and bending moment, the residual strength of these structures accounting for impact induced damage is one of the most detrimental situations...

... Abstract Based on the date of RFT (Remote Field Technology) and FEM (finite element method), the failure behavior and residual strength of multiphase pipeline with corrosion defects exposed to internal pressure are studied. The mechanism of riser corrosion is discussed as well. From the FE...

.... Finally, there were a total of 24 combinations of tests. Under the given testing conditions, the over-consolidated sample was sheared under drained condition until the residual strength formed with a sliding surface in the soil. After that, the shear test was ceased by reducing the shear stress to zero...

ABSTRACT For the last couple of decades various experimental and theoretical investigations have been performed on offshore tubular members related to their damage resistance and residual strength. Damaged tubular problems require 3-dimensional shell analysis for accurate results. Even though...
