Saurabh Dixit,Avik Mahata,Avik Mahata,D. Roy Mahapatra,Satish V. Kailas,Kamanio Chattopadhyay +5 more
TL;DR: In this paper, a multi-layer graphene embedded composite of aluminium alloys by direct exfoliation of graphite into graphene with the help of Friction Stir Alloying (FSA) was reported.
Journal ArticleDOI
Integrating strong and weak discontinuities without integration subcells and example applications in an XFEM/GFEM framework
TL;DR: Numerical results presented for a few benchmark problems in the context of linear elastic fracture mechanics and a multi-material problem show that the proposed integration technique can be easily integrated in any existing code and yields accurate results.
Journal ArticleDOI
Finite element analysis of free vibration and wave propagation in asymmetric composite beams with structural discontinuities
TL;DR: In this article, a locking free first-order shear deformable finite element is presented, and its utility in solving free vibration and wave propagation problems in laminated composite beam structures with symmetric and asymmetric ply stacking is demonstrated.
Journal ArticleDOI
Description of a new method of ovariectomy in female rats.
TL;DR: An efficient method of ovariectomy is reported and this method was technically easier, less time consuming and showed less wound healing duration than the two other operative methods.
Journal ArticleDOI
Characterization of a large-area PVDF thin film for electro-mechanical and ultrasonic sensing applications
TL;DR: In this article, large-area PVDF thin films have been prepared and characterized for quasi-static and high frequency dynamic strain sensing applications and the linear strainvoltage relationship obtained is promising.
