Impact characterisation of doubly curved composite structure [PDF]

open access: yes, 2009
Under repeated impact composite domes subjected 6 J energy, changes locally with increasing drop height. The action of the dynamic load generates reactions at the support and bending moments at points on the surface of the composite.

Atmospheric Structure and Composition

open access: yes, 2009
Titan's atmosphere is predominantly N2 with CH4 the next most abundant molecule. It has a mole fraction of 0.05 just above the surface decreasing to 0.014 in the stratosphere. Above the homopause (~800–850 km), it increases to 0.12 at the exobase. The third abundant molecule is H2 with a tropospheric mole fraction of 0.001 increasing to 0.004 at ~1000 ...

Atomistic simulations of the graded residual elastic fields in metallic nanowires

open access: yesResults in Physics, 2021
The local inhomogeneity of bonding environments in nanomaterials should lead to non-uniform distributions of the surface-induced residual stress and strain (residual elastic fields), which is inconsistent with the conventional assumption of uniform ...
