Example calculation

Evaluating protection against collapse from buckling and estimation of maximum permissible loading time

for cylindrical shells subject to compressive stress in accordance with 2015 ASME BPVC Section VIII Division 1 using alternative safety factor from Jawad & Farr GUIDEBOOK 1998

Attention!
This calculation is only a simplified estimation, and does not replace a detailed design calculation.
