Fracture Toughness Evaluation for Magnetostrictive Problem using COMSOL Multiphysics®

A. Bhushan [1], Prof S.K. Panda [1],
[1] Indian Institute of Technology (Banaras Hindu University), Varanasi, Uttar Pradesh, India

Even though failure due to the presence of flaws, inclusions, cracks or crack like defects has been observed in structural components operated under magnetic fields. The creation of the ferrous man-made structures, however, the formulations of various fracture theories and the ... En savoir plus

Low-Loss Metallic Waveguide for Terahertz Applications

K.Singh [1], A.Sengupta [1], A.Bandyopadhyay [2],
[1] Indian Institute of Technology Delhi, New Delhi, India
[2] DRDO-JATC, New Delhi, India

Introduction: Terahertz waves (THz), also known as T-rays, range from 0.3 THz to 10 THz and hence positioned between Microwaves and Infrared radiations on the Electromagnetic spectrum. T-rays exhibit several distinctive properties which make these suitable for applications such as ... En savoir plus

FEM Design of Interferometric FBGL Based Accelerometer for Underwater Applications

Malu Balachandran [1], R Rajesh [1], Sreehari C V [1], Khansa C A [1], K P B Moosad [1],
[1] Naval Physical and Oceanographic Laboratory, Kochi, Kerala, India

Fiber optic sensors have been designed for applications ranging from simple proximity detectors to state of the art inertial navigation systems. The optical sensing technique used in each of these applications depends primarily on the requirements. Fiber Bragg Grating Laser (FBGL) based ... En savoir plus

Study of Bending Losses in Optical Fibers using COMSOL Multiphysics®

Ashitosh Velamuri [1], Krupal Patel [2], Ishan Sharma [2], Shakti Gupta [2], Pradeep Kumar Krishnamurthy [1],
[1] Center for Lasers and Photonics, Indian Institute of Technology Kanpur, Kanpur, Uttar Pradesh, India
[2] Department of Mechanical Engineering, Indian Institute of Technology Kanpur, Kanpur, Uttar Pradesh, India

In FTTH, optical fibers are frequently bent at the corners of the walls causing the propagating light in the fiber to radiate away which results in transmission losses and limits reach of the fiber network. A large number of studies have been reported in the literature to compute bend ... En savoir plus

Enhancement of Birefringence using Metal-filled Suspended Core Microstructured Optical Fibers

Rajat Kumar Basak [1, 2], Debashri Ghosh [1]
[1] CSIR-Central Glass and Ceramic Research Institute, Kolkata, West Bengal, India
[2] Jadavpur University, Kolkata, West Bengal, India

Microstructured optical fiber (MOF) has carved out a niche in the field of photonics in the last decade. On the other hand, the field of plasmonics is also rapidly emerging as a fascinating research area. Combining the advantages of both these fields therefore seems imperative for newer ...

Acoustics - Structure Interaction Studies of Fiber Optic Mandrel Hydrophne using COMSOL Multiphysics®

Ashida Pradeep [2], Sreehari C.V. [1], Lav Kumar [1], R Rajesh [1], Vivek K [1], K P B Moosad [1]
[1] Naval Physical and Oceanographic Laboratory, Kochi, Kerala, India
[2] Govt. Model Engineering College, Kochi, Kerala, India

Hydrophones are acoustic receivers, which can be used to listen to the sound propagating underwater for the purposes of monitoring marine life, or other sound producing activities in the sea. Commonly used hydrophones are based on piezoelectric transducers. With the introduction of fiber ... En savoir plus

Computational Analysis of Metal Hydride Reactor for Thermal Energy Storage

Aswin N. [1], Pradip Dutta [1], S. Srinivasa Murthy [2],
[1] Department of Mechanical Engineering, Indian Institute of Science, Bangalore, Karnataka, India
[2] Interdisciplinary Centre for Energy Research, Indian Institute of Science, Bangalore, Karnataka, India

Metal hydride based thermal energy storage systems belong to the category of heat storage systems which rely on reversible thermo-chemical reactions to store and release heat. Specifically, these systems utilize metal/alloy hydride decomposition (endothermic) and formation (exothermic) ... En savoir plus

The Acoustic Behavior of a Loudspeaker Mounted on Different Types of BIW (Body-in-white) Frames

Niranjan Ambati [1], F. Malbos [2], Michal Bogdanski [3], Michael Strauss [3],
[1] Harman International Private Limited, Bangalore, Karnataka, India
[2] Harman France SNC, France
[3] Harman Becker Automotive Systems, Germany

For automotive applications, simulations are used to optimize the position and orientation of a subwoofer (loudspeaker) in a very constrained space to get the best acoustic performances. One solution is to use particular part of the BIW volume as the subwoofer enclosure. The acoustical ... En savoir plus
