in the present study, modelling and vibration analysis of carbon nanotubes/ fiber/ polymer composite microplates are investigated. the governing equations of the carbon nanotubes/ fiber/ polymer composite microplates are derived based on first order shear deformation plate theory, rather than other plate theories, due to accuracy and simplicity of polynomial functions. the modified couple stres...

This paper presents the adaptive integral method (AIM) utilized to solve scattering problem of mixed dielectric/conducting objects. The scattering problem is formulated using the Poggio-MillerChang-Harrington-Wu-Tsai (PMCHWT) formulation and the electric field integral equation approach for the dielectric and conducting bodies, respectively. The integral equations solved using these approaches ...

This paper presents a nonlinear vibration analysis of functionally graded graphene platelet (GPL) reinforced plates on elastic foundations. Uniformly or non-uniformly distributed internal pores were present in the plates. Based modified Halpin-Tsai micromechanics model and extended rule mixture, material properties evaluated. The governing equations, coupled with effect foundations, derived by ...

Magnetism of Tsai-type 1/1 approximants has been extensively investigated for the last decade. The experimental results on are reviewed and magnetic behaviors classified discussed in terms average electron-per-atom (e/a) ratio. paramagnetic Curie-Weiss temperature ?p is found to oscillate a universal manner as function e/a ratio, order systematically changes with variation ?p. In addition, rece...

Recently, Tsai et al. proposed dynamic ID based smart card authentication scheme. This paper demonstrates that Tsai et al.’s scheme fails to provide early wrong password detection, secure password change and protection against insider attack. To overcome, we propose a secure SCAM (Smart Card based Authentication Mechanism) which keeps all previous merits and achieves security and functionality ...
