Evaluation of T-stress using FEM in an Unsymmetrical Cracks Emanating from a Hole Placed Centrally in a Thin Plate
Abstract: Studying the impact of higher order terms of the William’s series expansion on fracture mechanics problems has received more attention in recent years. Research has demonstrated that the constant term T-stress has a significant impact on the stress and strain fields around the crack tip. In response to mixed mode (I/II) loading, a number of fracture criteria had been developed to characterize failure in linear elastic bodies. When evaluating the …

Failure Analyses of 16 mm Thick SA 516 GR 70 Auto Clave
Abstract: With the acceleration of global industrialization, there is a demand for high-or low-pressure storage of liquids or gases. Because of the complicated operating conditions that will inevitably encounter a possible hazard, pressure vessel design is a critical responsibility. Previous failure studies have revealed that the presence of local loads and discontinuities increases pressure vessel fracture. As a result, a detailed examination of pressure vessel steel from the standpoint of fracture …

Exploring the Impact of Lattice Strain on the Debye-Waller Factor in Iron Nanoparticles: A Comprehensive Analysis
Abstract: This study systematically investigates the influence of lattice strain and particle size in iron powder produced through milling, employing X-ray powder diffraction. The determination of lattice strain (ε) and the Debye-Waller factor (B) is accomplished by analyzing Bragg reflection half-widths and integrated intensities. Significantly, the Debye-Waller factor exhibited a notable increase with lattice strain. By establishing a correlation between stress and the influential Debye-Waller factor, we derived a precise relationship …

Structural Performance Evaluation of Circular Perforated Plates under Mechanical Loading
Abstract: Circular perforated plates are structurally critical components in aerospace, automotive, and marine sectors, where perforation-induced stress concentrations govern failure under mechanical loading. This study conducts a systematic finite element analysis of stress distribution, deformation, and interlaminar behavior in aluminum and glass-epoxy laminates ([−45/45/90/0]S and [−45/45/90/0]AS) under uniform transverse pressure with clamped-free boundary conditions. Four perforation configurations—no hole, central hole, single-series, and 25-hole grid—were evaluated using ANSYS Shell-181, verified against Kirchhoff–Love, …

Climate Change and Urban Heat Islands in India: A Review Across Nine Urban Agglomerations
Abstract: Since 1901, anthropogenic climate change has raised India's mean surface temperatures by about 0.9°C, compounding warming. Rapid urbanization creates persistent Urban Heat Islands (UHIs), making cities dangerously hotter than rural areas. A combination of these forces presents acute thermal hazards to hundreds of millions of urban dwellers. The paper discusses the emergence and intensification of UHI in nine large Indian cities (Delhi-NCR, Ahmedabad, Chennai, Hyderabad, Kolkata, Pune, Bengaluru, Mumbai, and …
