Analysis of geogrid reinforced pond ash embankment using finite element method

The Pond Ash sample was collected from the ash pond site of Raj ghat thermal power station, Delhi, soil was collected from NIT campus, Srinagar and the lime was procured from the open market in the form of quick lime. This lime was then mixed with pond ash, by weight (= 9%) (Gupta et al, 2013).Further, in the present work an experimental program was carried out to characterize the materials and strength tests were performed to study the behaviour of pond ash mixed with lime; the results shows that in the presence of moisture, pond ash chemically reacts with lime at ordinary temperature and forms cementations material which is attributed to the increase in strength of pond ash. Numerical analysis was performed using the FEM based software PHASE2 (Roc science). Results divulge that use of full length of geogrid covering whole width of embankment increases the critical strength reduction factor (SRF) of embankment at steeper slope inclination. Also, the application of either geogrids layers or pond ash-lime mix layer, results in safer designs in comparison to unreinforced pond ash embankment.

Analysis of variation of hardness in TIG welded stainless steel alloy

AISI 304 SS (stainless steel) has similar mechanical property as compare to AISI 304 SS grade, but its ability to resist corrosion is somewhat less as compare to AISI 304 SS grade in chloride environment. But it is very inexpensive so we can use it in indoor applications like indoor fabrication, automobile trim and application where atmosphere is not a considerable factor. But there is very less research reported on welding of AISI 304 SS grade. In order to find out the weakest locations of the joints and determine the optimum MIG welding parameters, this present work aims to demonstrate its MIG weldability and the emphasis is placed on the relations of the tensile properties and hardness to the welding parameters

Review on MIG welded stainless steel alloy

MIG welding Arc voltage control, the energy source is given and the wire-feed unit delivers speed control of the welding wire, in MIG it is equivalent to the welding process. Many traditional wire feed systems control the wire feed speed through the thyristor control PCB and the DC motor to offer control of the Armature volts and therefore the RPM of the engine. The wire feed motor spindle is equipped with a feed roller and then additional pressure roller, the variable spring is placed to gently catch the wire and force it up to a MIG torch length

Review on TIG welded stainless steel alloy

The TIG welding device is soldered to increase welding efficiency in Stainless Steel 304 (SS-304) by modifying various welding parameters. Effects on the strength and toughness of the weld joint of solding current, gas flow rate (CO2) and welding speed were examined. Optical microscopic analysis on the welding zone was performed to determine the effect of soldering parameters on soldering efficiency. In order to understand the change in the mechanical features of a welded zone a micro-hardness value of the welded zone was measures on the cross section

Review Paper

A short review on recent technologies of food packaging

The present article focuses on the active and intelligent packaging of fresh foods in food industry. There are several packaging techniques for storing fresh foods in the market and several new technologies developed with or without carbon dioxide absorbers which improves the quality and therefore increases the shelf life of the product. Fruit quality has been checked by using different spectroscopy techniques. Various intelligent packages have been developed which improves the freshness of the food. Nanotechnology methods are useful for detecting the spoilage of the food such as inks, adhesives and usage of oxide barriers. Hence these are useful for increasing the safety of the food to the consumer. These also include toxic free and edible packaging material. New methods such as 3mtm monitor in the future can increase the development of the packaging in the food sector.
