© 2016 Springer-Verlag Berlin Heidelberg The static and dynamic behavior of a curved single-walled carbon nanotube which is under twist–bending couple based on nonlocal theory is analyzed. The nonlocal theory is used to model the mechanical behavior of structure in small scale. The obtained differential equations are solved using a simply supported boundary condition and Navier analytical method. Moreover the twisted vibration and bending of curved nanotube is analyzed and also the armchair model is assumed in this study. The following parameters were studied in this paper: the effect of nonlocal parameter, the curved nanotube's opening angel, the Young's modulus and the mode number is studied. The results were verified with the previous literature which showed an excellent agreement. The results of this paper can be used as a benchmark for future investigations.

© 2016 World Scientific Publishing Company. In this paper, we study the vibration of curved nano-sandwich (CNS) with considering the influence of core shear based on the Eringen nonlocal theory. The equation of motion is derived and exact solution for the natural frequencies of CNS is presented. The proposed nonlocal model includes a material length scale parameter that can capture the size effect in CNS beam. The effects of important parameters, such as the thickness to length ratio, nonlocal parameter and mode number on the frequencies of CNS are investigated. The result of our research shows that as the opening angle increases, the amount of natural frequencies decrease. We have additionally validate, our results against previous research works which showed good agreement.

Rapid quadrupedal movement on granular media and other irregular terrain is an interesting area of research which is under-explored. Current methods of studying rapid quadrupedal movement involve the measurement of ground reaction forces (GRF) using a force plate and a simultaneous kinematics analysis by a High Frame Rate video (HFR). Although force plates provides highly accurate kinetic data, it is not always practical to deploy in the study of animal locomotion. For instance, it is often not possible to embed force plates in irregular terrains  characteristic of most ecologically relevant animals' natural habitats . An alternative method is to utilize an inertial measurement unit (IMU) equipped with a tri-axial accelerometer to analyze accelerations associated with different quadruped gaits. In this study, a tri-axial accelerometer is used to analyze sprinting locomotion dynamics of a greyhound in a simulated racing condition. Kinematics data from videography of the entire race was recorded in each trial for data calibration. In addition, the paw prints of the greyhound on a sandy-loam surface of a race track are also analyzed to sync acceleration data with each individual paw print.
