(b) Stiffness at small strain
The general relationships between shear modulus
G
and strain, state and history
for small strains in the range 0.001% to 1% are illustrated in Fig. 13.10 and
the same general relationships hold for the other stiffness parameters. The value
of
G
/
p
depends on strain (because of the non-linearity) and on ln
