Vibration analysis of multi-walled carbon nanotubes embedded in elastic medium
TL;DR: In this article, a method to estimate the natural frequencies of the multi-walled carbon nanotubes (MWCNTs) embedded in an elastic medium is proposed, in which each of the nested tubes is treated as an individual bar interacting with the adjacent nodes through the inter-tube Van der Waals forces.
Journal ArticleDOI
Risedronate/zinc-hydroxyapatite based nanomedicine for osteoporosis
Deepak Kumar Khajuria,Deepak Kumar Khajuria,Choudhary Disha,Ramakrishna Vasireddi,Rema Razdan,D. Roy Mahapatra +5 more
TL;DR: Therapy with risedronate/ZnHA drug formulation prevented increase in serum levels of bone-specific alkalineosphatase and tartrate-resistant acid phosphatase 5b better than risedronsate/HA or risingronate therapy and preserved the cortical and trabecular bone microarchitecture better than the former.
Journal ArticleDOI
Guided wave based detection of damage in honeycomb core sandwich structures
TL;DR: In this paper, a Lamb wave type guided wave propagation in honeycomb core sandwich structures is presented. And the authors show the potential of Lamb wave-type guided wave for detection of damage in sandwich structures.
Journal ArticleDOI
Mechanical properties of Graphene: Molecular dynamics simulations correlated to continuum based scaling laws
Brahmanandam Javvaji,Pattabhi R. Budarapu,Vijay Kumar Sutrakar,D. Roy Mahapatra,Marco Paggi,Goangseup Zi,Timon Rabczuk +6 more
TL;DR: In this paper, the combined effect of domain size, lattice orientation and crack length on the mechanical properties of Graphene, namely the yield strength and strain, are studied extensively based on molecular dynamics simulations.
Journal ArticleDOI
Single and multi-step phase transformation in CuZr nanowire under compressive/tensile loading
TL;DR: In this article, a novel stress induced martenistic phase transformation is reported in an initial B2-CuZr nanowire of cross-sectional dimensions in the range of 19.44 x 19.88 x 38.88 angstrom(2) and temperature in the ranges of 10-400 K under both tensile and compressive loading.
