This paper reports an investigation of the influence of initial stress on the flexural vibration of an individual multi-wall carbon nanotube with simply supported ends, based on a laminated elastic beam model considering the van der Waals force interaction between two adjacent nanotubes. The results obtained show that the influence of initial stress in carbon nanotubes on their natural frequency is...
A micromechanics analysis is carried out for delamination cracking in functionally graded coating/substrate systems. The FGM coating is taken to be a ceramic/metal composite with its thermomechanical properties changing with position in the coating along the thickness direction. Based on a linear fracture mechanics analysis, the energy release rate of the delamination crack is determined as a function...
