A Model for Plastic-Hydrolytic Damage Bioresorbable Polymer Composites
Abstract: This paper explains and assesses a recently developed constitutive model for elastic-damage that may sustain plastic-hydrolytic damage. When a metallic material is subjected to plastic strain, voids and microcracks in the metal matrix start to form, develop, and merge. This is what causes ductilitydegradation in metals. Only a few of the many models that have been presented to depict ductile failure have done a thorough analysis of the entire damage …

Experimental Investigation To Study the Effect of Heat Treatment on Mechanical Properties and Microstructure of Duplex Stainless Steel
Abstract: The broad aim of this paper is to study the enhancement in mechanical properties of duplex steel by thermomechanical processing. Solution annealing followed by water quenching, hot rolling to 10% and 30%, cryo-rolling to 80% and 90% and ageing at 600°C and 1000°C for 5 hrs were the treatments given. The cryo-rolled samples were used for impact testing and rest for tensile testing. Microstructural analysis was done after the various …

A Brief note on Biomechanics
Abstract: Biomechanics is generally referred to as the study of how the systems of living organisms from plants to animals, react to the various forces of nature and stimuli. Biomechanics is the science of dealing with effects produced by external and internal forces on the living body. The need to study biomechanics for any the particular case is necessary for every physical educator or coach, who is involved in teaching movement …

Stress Intensity Factor in Artificially Damaged Structures
Abstract: The presence of cracks in macrostructures creates heterogeneity which manifests itself by a change of the state of stress and strain in the structure. A crack in vibrating structures can lead to premature failure if it is not detected in time. Researchers have been working on the dynamics of cracked structures for decades to be able to monitor the structure and diagnose that fault at the earliest possible stage. In …

Hardened Steel an Appliance with Low Degeneration
Abstract: Combination of high hardness, toughness, and strain hardening capacities with reasonable ductility have privileged Hadfield steel in sectors such as mining, transportation, military, agricultural and earthmoving equipment. Micro- porosities formation during casting by last solidifying liquids at inter-dendritic spaces in directional solidification have been insidious crack initiators during service exposure. Particulate penetration resistant wear part surfaces for secondary and tertiary crushers are found to add chromium and vanadium prone to …

Study the effect of lubrication on hardness in the ring compression test
Abstract: Mild Steel is commonly used to produce automotive parts such as shafts, gears and bearings. This paper focuses on the hardness distribution in the mild steel ring specimen after compress under rigid dies. Three different types of lubricants namely boric acid, Vaseline, grease and dry condition were employed as lubricants and the coefficient of friction corresponding to the lubricant evaluated using standard ‘Ring compression test’. The strain distributions obtained from …

Numerical Study of Vibration Stress and Deformation of Rotating Fan Blade of a Gas Turbine
Abstract: The vibration stress caused by resonance is the main cause of failure in aircraft engine blades. The study is aimed at investigating the vibration stress of a single-stage fan blade influenced by the interaction of aerodynamic and structural behavior at multiple critical speeds. A three-dimensional finite element model of the blade was developed for the simulation of vibration stress and its subsequent effects. The blade was verified by modal test. …

Structural Mechanics: Its Boundary Conditions and Applications
Abstract: Structural mechanics is the study of the calculation of deformations, deflections, internal forces, orstresses (stress equivalents) within structures, either for design or for performance assessment ofalready-existing structures. An area of structural analysis is this. Structural loads, the geometricrepresentation and support circumstances of the structure, as well as the material properties, are allinput variables for structural mechanics analyses. Support responses, strains, and displacementscould all be included in the output numbers. The …

Evaluating the Impact of a Structured Teaching Program on Chronic Obstructive Pulmonary Disease Prevention Among Guntur's Cotton Mill Workers
Abstract: Introduction: Chronic obstructive pulmonary disease result from increase d resistance to airflow because of airway obstruction or airway narrowing. COPD is an advancing inflammatory condition marked by persistent blockages in the bronchial tubes and pulmonary emphysema. It's a disabling ailment manifesting in symptoms like long-term cough, phlegm, wheezing, breathlessness, and heightened respiratory infections. Lung alterations lead to increased mucus production, impaired cilia function, restricted airflow, lung expansion, irregular gas exchange, …
