element solution are expected to be more accurate than those calculated using an
analytical solution.
FIGURE P12.11
12.12 Figure P12.12 shows the values of the torsional constant for several configurations
that are frequently given in handbooks. Use a computational solution to see how
close you can come to these values.
FIGURE P12.12
12.13 Verify the shear form factors of Fig. P12.12. Use a finite element solution.
12.14 Textbooks usually list the shear center for the configuration of Fig. P12.14 to be located
at y S =
3 b 2 t f [ ht
ω +
3 bt f /
2]. Is this an accurate expression?
