 Right click on Mode button in Total Deformation window
and change 1 to 2. Right click on Total Deformation and
select Evaluate All results, the second mode shape will
appear as shown in the figure with the computed Load
Multiplier of 19,881.

8.1.3 Application

Buckling of Detergent Bottle
A detergent bottle, lying down in the horizontal z-
direction as shown in the figure, is made from polyethylene
material that has the Young’s modulus of 1.1 10 N m 9 2 and the
Poisson’s ratio of 0.42. The bottle is subjected to an external
compressive loading in the z-direction of 5 Kg. In addition, the
