摘要: Abstract In this paper, the buckling behavior of a complete spherical shell under external pressure and half-sphere torsion are first investigated. Several parametric studies performed, which rely on European Recommendations framework (ECCS text), so as to identify different key parameters corresponding capacity curves lead up both qualitative quantitative discussion about imperfection sensitivity such structures each fundamental load. The related results allow us completely describe combined circumferential shear by means interactive curves, without need many supplementary computations for any arbitrary loading case.
