Analysis of Q345C Steel using Johnson-cook Constitutive and Damage-fracture Model Parameters

Diekman Duncheva*

DOI: 10.37421/2472-0437.2024.10.255

The structural integrity and performance of steel materials are critical factors in various engineering applications, ranging from automotive manufacturing to infrastructure development. Understanding the mechanical behavior and response of steel under different loading conditions is essential for ensuring the safety and reliability of engineered systems. In this study, we analyze the mechanical properties of Q345C steel using the Johnson-Cook constitutive model and damage-fracture model parameters. Through experimental testing and numerical simulations, we aim to characterize the material behavior, predict deformation, and assess fracture initiation and propagation in Q345C steel. The findings provide valuable insights into the mechanical response of steel under complex loading conditions and contribute to the development of accurate predictive models for engineering design and analysis.

DOI: 10.37421/2472-0437.2024.10.254

In modern civil engineering, the quest for sustainable construction materials has led to the exploration of alternative reinforcements in concrete structures. One such promising solution is the integration of Glass Fiber Reinforced Polymer (GFRP) bars with steel bars to form composite bars. This study delves into investigating the bonding performance of sustainable steel-GFRP composite bars in reinforced concrete structures. Through a comprehensive experimental program and analytical assessment, this research aims to evaluate the bond strength, durability, and structural performance of these composite bars. The findings are crucial for advancing the understanding of sustainable construction practices and promoting the adoption of eco-friendly materials in the construction industry.

Coating Steel Discs with a Photocatalytic CuO/SiO2 System for the Degradation of Methylene Blue and Amoxicillin Contaminants

Renouf Mitra*

DOI: 10.37421/2472-0437.2024.10.255

The contamination of water sources by organic pollutants such as Methylene Blue (MB) and pharmaceutical residues like Amoxicillin (AMX) presents significant environmental and public health challenges. Traditional wastewater treatment methods often struggle to effectively remove these persistent contaminants. Photocatalytic degradation using semiconductor-based materials has emerged as a promising approach for pollutant removal. In this study, we investigate the application of a CuO/SiO2 photocatalytic system for coating steel discs to facilitate the degradation of MB and AMX contaminants. Through experimental analysis and characterization, we assess the photocatalytic activity, stability, and efficiency of the coated steel discs under simulated solar irradiation. The findings contribute to the development of sustainable remediation technologies for water pollution control.
