Recent developments in the finite element analysis of prestressed concrete reactor vessels
TL;DR: In this paper, a number of finite element models are called into attention for the idealization of composite structures such as reinforced and prestressed concrete components, and different inelastic constitutive models are proposed for the behaviour of concrete in the pre- and post-failure regime.

Torispherical Shells under Internal Pressure—Failure due to Asymmetric Plastic Buckling or Axisymmetric Yielding
G D Galletly,Jan Błachut +1 more
TL;DR: In the diameter-to-thickness range 250 < D/t < 1000, internally pressurized torispherical shells can fail either by plastic buckling or by axisymmetric yielding as mentioned in this paper.

A refined curved element for thin shells of revolution
E. P. Popov,P. Sharifi +1 more
TL;DR: A refined axisymmetric curved finite element for the analysis of thin elastic-plastic shells of revolution is described in this paper, which is obtained by employing cubic polynomials in terms of local Cartesian co-ordinates for the assumed in-plane and out-of-plane displacements.
