6.5 The twisted strip shown below has a load F = 10 N. The dimensions and
−6
material constants are: b = 1.1 m, L = 12 m, t = 0.0032 m, E = 29 × 10 N/m , and

ν = 0.22. The strip has a 90° twist over length L and is cantilevered. Use shell ele-
ments to find the maximum displacement and von Mises stress in the structure.

6.7 Consider a glass cup placed on a table, as shown in the figure. Using shell ele-
ments, find the maximum displacement and von Mises stress in the cup when
the cup is applied with a pressure load of 10 N/mm on the inner wall. Assume
2
that the cup has a uniform thickness of 4 mm, E = 70 GPa, and ν = 0.17.
