Permeable textiles, used in association with geotechnical engineering related material, as an integral part of a man made project is called GEOTEXTILES. It has the ability to filter, reinforce, protect and drain. JUTE, a wholly renewable, bio degradable, naturally available geo textile is produced in abundance in India. Design of pavement using JGT is a boon to rural roads which enhances the aesthetic appearance also with benefits in lifecycle increment. Fortunately the economic aspect also in acceptance range. Coupled with the software analysis of designing a JGT incorporated road and comparing the ordinary flexible pavement, jute geotextile incorporated flexible pavement last longer than the usual roads

The paper outlines an experimental study to explain the effect of various process parameters on hard turning of EN19, is a high quality alloy steel which is heat treated to 50HRC. Four parameters were chosen as process variables: Speed, Feedrate, and Depth of cut and coolant flow rate. Surface roughness, tool-work piece interface temperature, and Material removal rate are selected as responses. Design of experiment is prepared using Box-Behnken designs in Response surface methodology and 28 experiments were performed on a CNC lathe. Minitab-17, a software environment for statistical computing and graphics is applied successfully for analyzing the effect of different process parameters. An attempt is be made to optimize the cutting parameters using Multi Objective Genetic Algorithm in the focus of attaining minimum surface roughness, minimum work piece temperature and maximum material removal rate.Confirmation experiments were performed in order evaluate the effectiveness of the generated result

An actuator is a mechanical device that takes energy created by air, electricity, liquid and converts it into motion. In the present study, the design of actuator cylinder using 15-5 PH (H-1025) stainless steel is considered. The dilation, weight, time and cost of fabrication of current design is high. The final component when incorporated into the destination adds weight as a whole due to its density. The present work focussed on replacing the existing material with a SiC particle reinforced aluminium metal matrix composite to reduce weight, dilation and fabrication cost of the actuator. To achieve these objectives two step-mixing method of stir casting technique has been adopted and subsequent property analysis has been made. Aluminium alloy 6061 and silicon carbide (500 grit size) has been chosen as matrix and reinforcement material respectively. T6 heat treatment also improves the material properties. The material properties are then validated using transient structural analysis in ANSYS Workbench and the design is found successful in reducing weight of actuator. Cost analysis is conducted and actuator cylinder with Al-SiC composite material came out to be a potential substitute for the existing design.
