Abstract- This study aims to predict the elastic-plastic fracture toughness of ductile material using Finite element modeling ‘for which we predict the variation of SZW and critical SZW under mix mode condition and we also use mix mode mixidity. In our findings significant variation in the magnitude of critical SZW on the two surfaces were noticed. This is differing in pure mode-I and mode-II. It is due to variation in mode mixidity at different plane levels. Insignificant variations of average critical SZW were observed upto 45° (mid thickness) i.e. 45° while, after 45° significant reduction in average critical SZW value were observed. In addition, the significant change in sharp crack front of the magnitude of ….
Abstract- Now-a-days, adjustable speed drive has became a significant load component for power distribution system. It involves the use of Induction motors (Wound rotor type & squirrel cage ) The paper here is based on analysis, control and modeling of induction motors and also investigates its effects on Total current harmonic distortion on an adjustable speed by the use of ….. PWM generator and Vector control method. With the help of Park’s transformation ,we can convert three phase system to two phase and then it can be converted into two axes system (d, q). By ….
Abstract- The present paper is a review of research work of heat transfer growth in circular tubes for laminar and turbulent flow. Active as well as passive methods are employed for increasing the heat transfer coefficient in circular tube; Passive methods do not require application of external power such as active method require. The effectiveness of both active and passive methods depends strongly on the mode of heat transfer, which might range from single phase free convection to dispersed flow film boiling. Passive techniques, where inserts are used in the flow passage to augment the heat transfer rate, are advantageous compared with active techniques, because the insert manufacturing process is simple and these techniques can be easily employed in an existing heat exchanger. In design of compact heat exchangers, passive techniques ….

Abstract-Thermoplastic composites have great significance in automotive market due to their recyclables and high performance. PEEK composites actually ‘Polyetheretherketone’ have been extensively studied because of the excellent taluminium spokesological behavior among plastics. PEEK polymer, is increasingly used in many industrial applications as a replacement ….
