Analysis of Steel Chip Fiber Reinforced Composite Dual Pile Under Lateral Load Conditions on Sloping Terrain
Abstract: Pile foundations, in addition to supporting vertical loads from superstructures, are subjected to lateral stresses arising from seismic activities, wind gusts, water currents, and traffic impacts etc. Failure to account for these lateral forces can pose significant risks if the structure is expected to encounter any form of lateral pressure. Previous research has investigated the behavior of individual composite piles under horizontal forces, considering different soil properties, to determine the …

Flexural Response and Numerical simulation of Unidirectional Areca–Pineapple Leaf Fiber Hybrid Epoxy Composites
Abstract: The increasing demand for lightweight and environmentally sustainable materials has accelerated the development of natural fiber-reinforced polymer composites for engineering applications. In the present study, unidirectional areca and pineapple leaf fiber (PALF) reinforced hybrid epoxy composites were fabricated using a simple hand lay-up process. Before fabrication, the fibers were chemically treated to improve fiber–matrix adhesion and enhance the mechanical performance of the laminates. Four different stacking sequences (A8, A7P1, A6P2, …

Structure–Property-Guided Polymer–Metal Hybrid Design of a Wall Plastering Spray Assembly
Abstract: Wall plastering spray equipment requires a combination of low mass, dimensional stability, abrasion resistance, chemical compatibility with cementitious mortar, and comfortable operator interaction. The original assembly was primarily developed as a metallic mechanical system; however, a polymer-focused material architecture can reduce non-load-bearing mass while retaining a safe metallic pressure path. This study, therefore, presents a structure–property-guided polymer–metal hybrid design in which the pressure housing and nozzle insert remain metallic, whereas …

The Role of Polymer Chemistry in Developing a Novel Polymer-Based Retromolar Endotracheal Tube
Abstract: This study presents the development and characterization of a novel polymer-based modified endotracheal tube designed for retromolar intubation. The tube is manufactured using medical-grade polyvinyl chloride (PVC) with reinforced polymeric structures to enhance flexibility while maintaining lumen integrity. The incorporation of a preformed lateral curvature mitigates airway resistance and airflow reduction caused by manual bending, ensuring an optimal balance between rigidity and adaptability. Additionally, the integration of polymer-based ligature wires …

Performance of GFRP Bars in Flexural Members: A Comparative Study with Metal Bars Using FEA and Experimental Study
Abstract: In recent years, GFRP bars have been introduced as a replacement for metal bars as reinforcement in flexural members. This study evaluates the use of GFRP bars as the main reinforcement in flexural members such as beams through computer simulations and experimental work. A 4-meter beam from a sample structure, analyzed as per IS 875 (1987) Part 2, was considered for the study. This beam was designed considering both metal …

Cubic B-splines for Isogeometric Analysis of Laminated Composite Plates Subjected to Hygroscopic Loading Using Classical Laminated Plate Theory
Abstract: Composite laminates are inevitably used in several engineering structures due to their high strength and stiffness to weight ratio. The laminates are subjected to change in moisture content and the flexural behavior leads to change in the strength. Presence of moisutre may induce residual stresses and strains. Isogeometric analysis is a well-proven method to perform analysis of laminated composite plates. The main focus of this study is to apply isogeometric …

Analysis for Pier of Railway Bridge
Abstract: The load-bearing capacity of a pier is determined by the combined effects of the load from the train and the self-weight of the girder it supports. The bending of the pier is influenced by its height, which necessitates a careful assessment of the pier's thickness across various girder spans and pier heights. This evaluation ensures that the pier can withstand the imposed loads while adhering to permissible deflection limits. By …

Review of Subsea Pipeline for Minimizing Thermal and Pressure Expansion
Abstract: As the offshore oil and gas fields have been exploited in deeper water, subsea pipelines are required to operate at high temperatures and pressures. It causes subsea pipelines to be more subject to movements both in lateral and axial directions due to the loads produced by high temperatures and pressures. Some high temperature pipelines have experienced the cumulative axial displacement of an overall pipeline length over a number of start-up/shut-in …
