A Review on Process Parameters Optimization of WEDM for Metal Matrix Composites
Abstract: Wire electrical discharge machining (WEDM) is a thermal spark erosion type cutting process used for precisely machining parts with intricate shapes and sharp edges that are difficult to machine by the conventional machining processes. The WEDM process is derived from conventional EDM sparking phenomena utilizing the noncontact type technique for material removal. From the time of introduction of the process, WEDM has emerged as alternative for production of micro-scale parts …

A Review on Application of Biogeography-based Optimization in Mechanical Engineering
Abstract: Engineers are always keen to learn from nature. This motivates development of optimization techniques from mathematics of biogeography called as biogeography-based optimization (BBO). This method can be very useful in some mechanical simulations as they are complex and computationally expensive. In this paper, survey on the application of biogeography-based optimization and its modified approaches in mechanical engineering has been provided.

Development of a Self-Supported Portable Pre-Tensioning System for Slab Panels
Abstract: Application of pre-stressed pre-cast elements has gained a lot of popularity over the years. The advantage obtained from pre-cast construction is the high control over its quality, and easy and fast on site construction. The short comings encountered in the application of such elements have been; the requirement of heavy machinery for pre-stressing and the transportation of these elements from yard to site. In order to address these shortcomings, an …

Experimental Techniques for Fatigue Analysis of a Small Wind Turbine Blade
Abstract: During the life span, a wind turbine blade experiences variety of the forces. These forces include gravitational force, centrifugal force, tangential force, thrust force, etc. Thrust force and gravitational forces create edgewise bending stress while the tangential forces (wind pressure) create flapwise bending stress. Centrifugal forces generate direct stress in the wind turbine blade. Most of the wind turbine blades fail due to bending in the flapwise direction. These induced …

Modified Double-Diffusive Convection in Viscoelastic Fluid
Abstract: Normal 0 false false false EN-IN X-NONE X-NONE MicrosoftInternetExplorer4 Modified double-diffusive convection in viscoelastic fluid of the Veronis’ and Stern’s type configurations is considered in the present paper. Semi-circle theorems that prescribe upper limits for the complex growth rate of oscillatory motions of neutral or growing amplitude are derived. The limits so derived naturally culminate in sufficient conditions which precludes the non-existence of such motions. The results obtained herein significantly …

Precise Modeling Practice for Avionics PCB in Random Vibration Environment
Abstract: Electronic packaging analysis fraternity makes use of finite element method (FEM) to predict random vibration response experienced by printed circuit board (PCB) of any avionics electronic package. Degree of accuracy associated with such prediction enables the connoisseur to make apt verdict while ascertaining the design adequacy of the package. Achieving accuracy in prediction is dictated by the preciseness associated with the modeling practices adopted in FEM. Precision of a particular …

Design, Development and Experimental Investigation of Biflex Mechanism for High Precision Applications
Abstract: Present article highlights at the achievement of XY mechanism that utilizes fundamental building elements, for e.g, beam of cantilever structure, double parallelogram and parallelogram flexural structures with respect to their execution aspects like parasitic error and stiffness. Distinguishing amongst biflex mechanisms is done in view of various parameters like stiffness, parasitic flaw and angular movement of deformation stage. Theoretical and finite element analysis is done for this and it is …
