Buckling of thin-walled orthotropic cylindrical shells under uniform external pressure. Application to corrugated tin cans

摘要

The general instability of thin-walled orthotropic circular cylindrical shells under external pressure is investigated. The buckling pressure can be predicted with the use of simple analyti- cal formulae derived from an asyniptotic analysis of the corresponding eigenvalue problems. The results predicted by these formulae are compared with finite element solutions and the four types of experimental models investigated by Ross (Thin Walled Structures 1996,26(1)179-93). The compurison proved to be accurate enough for practical purpose except for experimental model .
