چکیده

The objective of this study is to present a potential mechanism for traumatic brain injury resulting from a lateral blunt impact to the head during SUV-to-pedestrian impact. We developed an AM50 percentile model of the human head, and the mechanical response predicted by the model was validated against available cadaveric test data. It was found that the traction force due to the inertia of the brain mass plays a key role in brainstem lesion prior to the primary contact as well as the local stress/strain distribution around the lateral ventricle immediately after the contact with a vehicle.

On the response spectra of cracked beams under different types of moving force

In this paper, the dynamic responses of cracked beams under different moving forces, including moving load, moving mass, moving oscillator, and four-degrees-of-freedom moving system, are investigated. Structural elements such as beams are designed to withstand the predicted loads, but unfortunately, they are always exposed to unpredictable damage such as cracks. Several factors may cause these ...

Buckling of nanotubes under compression considering surface effects

In this paper, the modified Euler-Bernoulli beam model is presented to examine the influence of surface elasticity and residual surface tension on the critical force of axial buckling of nanotubes in the presence of rotary inertia. An explicit solution is derived for the buckling loads of microscaled Euler beams considering surface effects. The size-dependent buckling behavior of the nanotube d...

Transverse vibration and instability of fluid conveying triple-walled carbon nanotubes based on strain-inertia gradient theory

In this paper, the transverse vibration of a triple-walled carbon nanotube (TWCNT) conveying fluid flow is studied based on the strain/inertia gradient theory with van der Waals interaction taken into consideration. The nanotube is modelled using Euler-Bernoulli beam model and the Galerkin’s method is employed to obtain the CNT complex valued Eigen-frequencies. The effects of the fluid flow tho...
