ClearLow temperature impact toughness of the main gas pipeline steel after long-term degradation
This engineering study examined how long-term in-service degradation affects the low-temperature fracture toughness of gas pipeline steel, finding correlations between microstructure changes and reduced impact resistance over time. This is an industrial materials science study with no relevance to microplastic pollution.
Influence of structural and physical degradation of the stressed metal of pipes on the damage of main gas pipelines
Researchers examined the mechanisms by which structural and physical degradation of stressed pipeline metal contributes to stress corrosion cracking in main gas pipelines, analysing regulatory approaches and diagnostic methods. They found that hydrogen concentrating in near-surface metal layers — facilitated by tensile stresses — promotes microplastic deformations that intensify crack propagation, identifying surface layer defects as the primary driver of corrosion-mechanical failure.
A review of fatigue crack growth for pipeline steels exposed to hydrogen
This review examines how exposure to pressurized hydrogen accelerates fatigue crack growth in pipeline steels, a concern for hydrogen energy transport infrastructure. This structural engineering study has no connection to microplastics or environmental health.
Defectiveness of External and Internal Surfaces of the Main Oil and Gas Pipelines After Long-term Operation
This engineering paper analyzes corrosion damage in oil and gas pipelines after long-term operation, identifying causes of surface defects and material degradation. This study is focused on industrial infrastructure safety and has no connection to microplastic pollution or human health.
Investigation of Hydrogen Embrittlement Susceptibility and Fracture Toughness Drop after in situ Hydrogen Cathodic Charging for an X65 Pipeline Steel
This paper studied how hydrogen exposure affects the fracture toughness of X65 pipeline steel, which is used in oil and gas infrastructure. While not about microplastics directly, degraded or fractured pipelines are a potential source of plastic and hydrocarbon pollution in marine and coastal environments.
Effect of Cyclic Ice Plug Deformation on Microstructure and Mechanical Behaviors of Nuclear-Grade Low-Carbon Tubular Steel
Not relevant to microplastics — this is a metallurgy study examining how cyclic freeze-thaw ice plugging affects the dislocation microstructure and mechanical properties of nuclear-grade steel pipeline material.
Hydrogen in metallic alloys ─ embrittlement and enhanced plasticity: a review
This review traces the evolution of theories explaining hydrogen embrittlement in metallic alloys, focusing on hydrogen-enhanced decohesion and hydrogen-enhanced localized plasticity models. While not directly about microplastics, the research is relevant to understanding degradation of metallic materials in environments where microplastic-associated chemical interactions may accelerate corrosion.
1990 Plenary Lecture: Strain Rate Effects in Stress Corrosion Cracking
This materials engineering paper examines how strain rate governs stress corrosion cracking in metals, with microplastic deformation at the material level being a key mechanistic factor. The study applies to understanding pipeline and structural failures but uses 'microplastic' in a materials science context entirely unrelated to environmental plastic pollution.
Characteristics of Wires of the Long-Operated Aluminum-Steel Cable at Different Places on an Overhead Power Line Span
This materials science paper examines the structural and mechanical properties of aluminum-steel cable wires from long-operated power lines. This is an engineering paper with no direct relevance to microplastics or environmental health.
Validierung von Software-Komponenten zur Voraussage der strahleninduzierten Schädigung von RDB-Stahl
This German nuclear engineering report describes the development and validation of software tools to predict how neutron radiation damages reactor pressure vessel steel at the atomic through macroscopic scale. This is a nuclear materials science study with no relevance to microplastic pollution or environmental health.
Numerical Simulation of Inelastic Cyclic Response of Hss Braces Upon Fracture
This structural engineering study modeled the fracture behavior of hollow steel braces used in earthquake-resistant building structures, simulating how they fail under cyclic loading. This is a civil engineering study with no relevance to microplastic pollution.
A quantitative residual stiffness model for carbon fiber reinforced polymer tendons
Not relevant to microplastics — this engineering study models residual stiffness degradation in carbon fiber-reinforced polymer tendons under fatigue loading, relevant to civil infrastructure but with no connection to microplastic research.
A continuum damage mechanics model for fatigue and degradation of fiber reinforced materials
This engineering paper presents a mathematical model describing how fiber-reinforced materials degrade under repeated loading, using microplastic deformation as the driving mechanism for damage accumulation. It is a materials science study with no direct relevance to environmental plastic pollution or human health.
The influence of microstructure on the fatigue crack growth rate in marine steels in the Paris Region
This study examined how internal microstructure affects fatigue crack growth in marine-grade steel under seawater and air conditions, identifying three crack-influencing phenomena. The research pertains to offshore structural integrity and is not directly related to microplastics or human health.
Accelerated Hydrothermal Aging and Degradation Mechanism of PE100 Butt-Fusion Welded Joint
Researchers simulated the long-term aging of high-density polyethylene pipeline welded joints in water at various temperatures and found that higher temperatures caused more significant degradation of mechanical properties. The study used multiple characterization techniques to reveal changes in the molecular structure of the joints during hydrothermal aging. These findings help predict the service life of HDPE pipelines used in ocean energy transportation and inform strategies to mitigate aging-related failures.
Environmental stress cracking of chemically aged HDPE-100 gas pipe under impact fracture mode
This study examined how chemical aging — simulating long-term environmental exposure — affects the stress cracking behavior of high-density polyethylene (HDPE) pipes under impact conditions. Understanding how HDPE pipes degrade is relevant to microplastic pollution because aging plastic infrastructure releases small plastic particles into surrounding soil and water.
Empirical evaluation of the strength and deformation characteristics of natural and synthetic gas hydrate-bearing sediments with different ranges of porosity, hydrate saturation, effective stress, and strain rate
Not relevant to microplastics — this paper evaluates the mechanical strength and deformation of gas hydrate-bearing deep-sea sediments, relevant to methane extraction and the global carbon cycle but not to plastic pollution.
