  • Material Selection of LTCC Based Microstrip Patch Antenna Substrate Using Ashby's Approach
    2014 International Symposium on Computer Consumer and Control, 2014
    Co-Authors: Navneet Gupta
    Abstract:

    In this paper, different possible low temperature co-fired ceramic (LTCC) Materials for micro strip patch antenna substrates and their properties like, permittivity, dielectric loss, quality factor (Q-factor), temperature coefficient of the resonant frequency are taken into consideration and Ashby's approach is applied and based on the performance indices and Material indices, Material Selection Chart is plotted. The Selection Chart shows that Dupont-951 is the best Material for substrate application out of all possible candidates.

  • Material Selection methodology for gate dielectric Material in metal–oxide–semiconductor devices
    Materials & Design, 2012
    Co-Authors: B. Aditya, Navneet Gupta
    Abstract:

    Abstract Due to the continuous scaling of metal–oxide–semiconductor (MOS) devices, SiO 2 can no longer be used as a gate dielectric, so it has to be replaced by some suitable high- κ dielectrics. As there are variety of high- κ dielectrics available to designer, so there is a need for a proper technique to select the best possible Material. In this paper, we present a Materials Selection based on the Ashby’s methodology to optimize the choice of gate dielectric Material in MOS devices. In this work, performance indices and Material indices have been developed for gate Material in MOS devices and thereafter Material Selection Chart is plotted. The Selection Chart shows that La 2 O 3 is the most suitable Materials followed by HfO 2 and ZrO 2 for being used as gate dielectric in MOS devices.

  • Material Selection for electrostatic microactuators using Ashby approach
    Materials & Design, 2011
    Co-Authors: Ojasvita Parate, Navneet Gupta
    Abstract:

    Abstract Due to variety of Materials available to any designer for a particular application, there is a need for a proper technique to select. This paper focuses on the optimum Selection of Materials for electrostatic microactuators using Ashby approach. In this work, performance indices and Material indices have been developed for electrostatic actuators and thereafter Material Selection Chart is plotted. The Selection Chart shows that for high actuation voltage and high actuation force, diamond is the best possible candidate followed by silicon carbide and silicon nitride. On the other hand, if high speed electrostatic actuator is desired, then aluminum is the best possible candidate followed by nickel and copper.

  • Development of Material Selection method for the application children bicycle frame
    2010
    Co-Authors: Abdul Maleque, Dyuti Sarker
    Abstract:

    A bicycle frame is a crucial part for cycling performance, efficiency, comfort, and injury prevention. This is especially true in the case of children cyclists that do not have the necessary cycling experience, balance and the fully developed musculoskeletal system of the adults. The Selection of the correct Materials for a particular product especially a children bicycle frame is a key step in the design and development process because it will carry the load of the rider during cycling. In the present paper few methods have been developed to select Material of a bicycle frame for children and teenagers 7–14 years old. This paper will present the development of the Material Selection methodology based on Ashby’s Material Selection Chart for the application of bicycle frame purposes. Two quantitative methods are proposed such as cost per unit strength and digital logic model methods. Also mechanical properties, including tensile strength, yield strength, Young’s modulus, toughness, density as well as cost were used as the key parameters in the Material Selection stage. Among the Material Selection methods the development of digital logic model is the best suited method which identified that the Kevlar fiber reinforced plastics (KFRP) as the most appropriate candidate Material for the application of children bicycle frame.

  • MaterialS Selection OF A BICYCLE FRAME USING COST PER UNIT PROPERTY AND DIGITAL LOGIC METHODS
    International Journal of Mechanical and Materials Engineering, 2010
    Co-Authors: Abdul Maleque, S. Dyuti
    Abstract:

    The aim of this paper is to develop the Material Selection method and select the optimum Material for the application of folding bicycle frame. Two methods are introduced for the Selection of Materials, such as cost per unit property and digital logic methods. In cost per unit property, only one property (strength) is considered whereas in digital logic method, multiple properties such as tensile strength, yield strength, young’s modulus, toughness and density were considered for the optimum Selection of the Materials. The Ashby’s Material Selection Chart was used for the initial screening of the candidate Materials. The results are presented both in tabular and graphical forms. The Materials Selection method showed that AISI 1020 steel, Tialloy, carbon fiber reinforced polymer (CFRP), kevlar fiber reinforced polymer (KFRP) and glass fiber reinforced polymer (GFRP) are the candidate Materials for the design of bicycle frame. From the cost per unit property method it is found that the KFRP shows the least cost Material followed by AISI 1020 steel Material. The digital logic method also showed the highest figure of merit value for KFRP Material followed by AISI steel and Ti-alloy. Based on the developed Materials Selection method and analysis of the few candidate Materials it can be concluded that the KFRP is the suitable Material for the design and application of bicycle frame.
