Development of a Novel Analytical Framework for Investigating Non-Symmetric Deformation Behavior in Strip Rolling
Abstract: In recent years, the asymmetrical rolling process has attracted considerable research attention due to its ability to induce non-uniform deformation characteristics within metallic workpieces. In this context, the present study introduces a novel analytical framework for asymmetrical cold rolling based on an enhanced slab method, specifically designed to overcome the inherent limitations of existing analytical models when applied to a wide range of asymmetric rolling conditions. A newly developed mathematical …

Effect of Fly Ash on the Rheological and Filtration Properties of Palm Oil-in-Water Emulsion Based Drilling Fluid
Abstract: The emulsions are considered as most favourable drilling fluid to drill sensitive formations like shales. In this work, an attempt has been made to develop an emulsion using palm oil. The polymers and surfactant were added to the system to improve the emulsion mud characteristics. It was observed that these emulsions were showing favourable rheological properties and poor filtration control characteristics. But, poor filtration properties were further controlled by fly …

New Design Formulae for Safety and Precision in the Fatigue Engineering of Mechanical Components and Structures
Abstract: This paper introduces two new formulae, termed the Nori Fatigue Formulae, for determining the maximum allowable fatigue stress in mechanical components and structures with significant stress concentrations. These formulae will eliminate the usage of code-sensitive safety factors along with other factored values from the entire mechanical design engineering work, ranging from a safety pin to spacecraft. The first formula gives the maximum allowable fatigue stress in tension, and the second …
