Analysis of some critical aspects in hot machining of Ti-5553 superalloy: Experimental and FE analysis

引用

Defence Technology（防务技术） 2019年第3期15卷 344-352页

作者： Asit kumar parida Kalipada Maity Mechanical Engineering Department Indian Institute of Technology Delhi India National Institute of Technology Rourkela Mechanical Engineering Department India

In this study, a newly developed titanium superalloy, i.e., the Ti-5553 alloy has used for hot machining. This material replaced Ti-grade-5 alloy in the application of aerospace, automobile, and biomedical sector. However, similar to Ti-grade-5 alloy, the Ti-5553 alloy has a low thermal conductivity which makes it difficult-to-cut material categories hence, high tool wear, cutting force and bad surface finish. Hot machining of Ti-5553 has been studied at different machining condition (room and hot) using Deform-2D finite element analysis. The result from the simulation test was compared with the experimental value and reduction of cutting and thrust forces was observed. The experiment was carried out with the same input parameters as simulation, and good coherence between them observed. Additionally, cutting zone temperature, effective stress, etc. for both room and elevated the temperature are also discussed.

Self-powered pressure sensor for ultra-wide range pressure detection

引用

Nano Research 2017年第10期10卷 3557-3570页

作者： Kaushik parida Venkateswarlu Bhavanasi Vipin kumar Ramaraju Bendi Pooi See Lee School of Materials Science and Engineering Nanyang Technological University Nanyang Avenue 639798 Singapore

The next generation of sensors should be self-powered, maintenance-free, precise, and have wide-ranging sensing abilities. Despite extensive research and development in the field of pressure sensors, the sensitivity of most pressure sensors declines significantly at higher pressures, such that they are not able to detect a wide range of pressures with a uniformly high sensitivity. In this work, we demonstrate a single-electrode triboelectric pressure sensor, which can detect a wide range of pressures from 0.05 to 600 kPa with a high degree of sensitivity across the entire range by utilizing the synergistic effects of the piezoelectric polarization and triboelectric surface charges of self-polarized polyvinyldifluoride-trifluoroethylene （P（VDF-TrFE）） sponge. Taking into account both this wide pressure range and the sensitivity, this device exhibits the best performance relative to that of previously reported self-powered pressure sensors. This achievement facilitates wide-range pressure detection for a broad spectrum of applications, ranging from simple human touch, sensor networks, smart robotics, and sports applications, thus paving the way forward for the realization of next-generation sensing devices. Moreover, this work addresses the critical issue of saturation pressure in triboelectric nanogenerators and provides insights into the role of the surface charge on a piezoelectric polymer when used in a triboelectric nanogenerator.

A local convergence analysis of Chebyshev-Halley method having third order of convergence for approximating zero of non-linear operator f(v) = 0 by using convex majorant function and their condition in B-space(Banach space), is presented in this article. We give the error estimate to show the efficiency of our study. Besides, we established the relation between majorant function and Kantorovich or Smale-type result as special cases of our general theory.
