Flexural Analysis of Concrete Specimens with Substantial Substitution of Cement by Marble Dust and Scrap Rubber as Fibre
Abstract: Concrete is a crucial material in building and construction. Concrete is becoming more and more in demand every day. Concrete's essential ingredients are running out, therefore we need to find replacements. In addition to providing the necessary strength to the concrete, the replacement materials should also have the properties of the genuine components used in concrete. Typically, compression is where concrete shines, whereas tension and shear are where it falters. …

Effect of Span, Load Intensity, and Beam Geometry on Stress and Deflection Behavior of RCC Beams
Abstract: This study investigates the influence of variations in beam geometry, span, load intensity, and permissible stresses on the structural behavior of reinforced concrete beams. Using classical bending and shear stress formulations, the effects of a 20% increase in key parameters were analytically evaluated. Results indicate that a 20% increase in beam span leads to a proportional 20% increase in beam depth, whereas a 20% increase in beam width or permissible …

Parametric Optimization and Stiffness Determination of XY Positioning Stage for High Precision Applications
Abstract: In micro-electro-mechanical system (MEMS) flexural mechanisms are widely used because of their advantages such as frictionless and wear less motion and high precision. Flexures depend on material elasticity for their functionality. In flexure mechanism, motion is generated due to elastic deformation of the beam from which it is made. One of the typical advantages of flexural mechanism is to gain precise deformation and flexibility to obtain motion in desired direction. …
