Figures

Grahic Jump Location
Section through spun toroid with top and bottom halves welded together (a); planar view of a toroid made by welding four, 90 deg, elbows (b,c)
Grahic Jump Location
Typical stress-strain curve for mild steel (obtained from 1.97 mm thick flat test coupon)
Grahic Jump Location
Bifurcation and collapse pressures for toroidal shell with circular cross section and r/t=18.74. The effect of two values of the yield point of mild steel, i.e., 194.8 and 400 MPa on the load-carrying capacity is shown.
Grahic Jump Location
Deformed shape just prior to buckling and the corresponding eigenmode for R/r=5 (a,b), and for R/r=15 (c,d). Other values are: r/t=18.74,σyp=194.8 MPa. Note: Deformations are not to scale.
Grahic Jump Location
Deformed shape at the collapse for R/r=5 (a), and for R/r=15 (b). Note: Deformations are not to scale.
