and kaolin-sand mixtures to evaluate shear modulus, damping ratio and
pore pressure of the mixtures. Test results reveal that shear modulus
increases with aggregate content and confining stress and decreases with
shear strain amplitude and loading cycles. Meanwhile, damping ratio depends
mainly on aggregate content and shear strain amplitude and is less affected
by loading cycles. Pore pressure also plays an important role in aggregate-kaolin
mixtures and increases with aggregate content. An attempt has also been
made to implement Artificial Neural Networks (ANNs) for modeling shear
modulus, damping ratio and pore pressure build-up in the mixtures. The
study indicates that ANNs can successfully model the complex relationship
between cyclic deformation properties and input parameters including current
state of stress, aggregate content, shear strain amplitude, confining
stress, aggregate size and loading cycles.]]>Akbulut, S., A.S. Hasiloglu and S. Pamukcu,2004Baziar, M.H. and Y. Jafarian,2007Garson, G.D.,1991Haykin, S.,1999Idriss, I.M., R. Dobry and R.D.
