RISMachine Learning Modeling for Predicting Tensile Strain Capacity of Pipelines and Identifying Key Factors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Machine learning (ML) techniques have recently gained great attention across a multitude of engineering domains, including pipeline materials. However, their application to tensile strain capacity (TSC) modeling remains ...
Tensile Strain Capacity of an X70 Pipe With Internal and External Semi-Elliptical Crack Under Bending and Tension
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper studies an in-depth examination of the tensile strain capacity (TSC) of an X70 pipeline containing an internal or external semi-elliptical crack when exposed to bending or tension. Comprehensive TSC evaluations ...
Effects of Loading Mode on Brittle Fracture of X70 Pipe Girth Welds
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A series of single-edge notched tension (SENT or SE(T)) and single-edge notched bend (SENB or SE(B)) testing was carried out at −15 °C using B × B specimens machined from two API X70 large diameter pipeline girth welds. ...
Damage Model Prediction of Crack Initiation and Propagation in Five Fracture Geometries for X80 Pipeline Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Test specimens used to calibrate damage-mechanics models are designed to produce a range of stress triaxialities and Lode angles to accurately capture the fracture envelope of the metal. Many of these specimens have lower ...
Characterization of Anisotropic Mechanical Properties of X70 Spiral Welded Steel Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Anisotropic tensile and compressive properties of base metals and girth welds of two API X70 spiral welded pipes have been investigated in this study. Spiral welded pipes exhibit different characteristics of anisotropy ...
Tensile Strain Characteristics of Small-Scale Fracture Toughness Test Specimens and Large-Scale Tests Under Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pipelines are susceptible to significant longitudinal deformation in areas affected by ground movements, including slope movement, frost heave, thaw settlement, and/or erosion. The assessment of tensile strain capacity ...
Evaluation of Two Low Constraint Toughness Test Methods in a Single Specimen
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In previous studies, the singleand doubleclip gauge methods were successfully consolidated in a singleedge notched tension (SE(T)) single specimen so that crack tip opening displacement (CTOD) values obtained from both ...
Low Constraint Toughness Testing of Two Single Edge Notched Tension Methods in a Single Specimen
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Singleedge notched tension (SE(T) or SENT) specimens have been increasingly proposed as a lowconstraint toughness test to measure toughness of line pipe materials, as the crack tip constraint approximates a circumferential ...
On the Crashworthiness of Steel Plated Structures in an Arctic Environment: An Experimental and Numerical Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Structural crashworthiness with regard to crushing and fracture is a key element in the strength performance assessment of ship collisions in the Arctic. The aim of this study is to investigate the crashworthiness ...
