Generally, thin cylindrical shells are susceptible for geometrical imperfections like non-circularity, non-cylindricity, dents, swellings etc. All these geometrical imperfections decrease the static buckling strength of thin cylindrical shells. In this work, neighbourhood effect of two circumferential short dents on the buckling behaviour of thin short stainless steel cylindrical shell is studi...

In this paper, the buckling behavior of a composite lattice cylindrical shell is studied and effects of rib defects on the distribution of stress field and buckling response of the shell is investigated. A three dimensional finite element buckling analysis of the lattice shell is carried out using ANSYS suit of program. Geometrical data and material properties of the shell are obtained from the...

Using  principle  of  minimum  total  potential  energy  approach  in conjunction  with  Rayleigh-Ritz  method,  the  electro-thermo- mechanical  axial  buckling  behavior  of  piezoelectric  polymeric cylindrical  shell  reinforced  with  double-walled  boron-nitride nanotube  (DWBNNT)  is  investigated. Coupling  between  electrical and mechanical  fields  are  considered  according  to  ...

This paper analyses Female Genital Mutilation (FGM), a traditional practice in many cultures in Africa (and countries with an African diaspora). FGM “is widely recognised as a violation of the human rights of girls and women” [1]. This paper follows mainstream academia: considering FGM as a type of violence against females – with harmful effects in both the short and long term [2]. Many researc...

While bulk bismuth (Bi) is a semimetal, we have found clear evidence of superconductivity in 72 nm diameter crystalline Bi nanowire below 1.3 K. In a parallel magnetic field (H), the residual resistance of the nanowire below T(c) displays periodic oscillations with H, and the period corresponds to a superconducting flux quantum. This result indicates that the superconductivity originates from t...
