How can I find the exess pore water pressure in my dynamic soil model

Submitted by alishafi on

Dear friends

I've prepared a dynamic model of saturated loose sandy soil with abaqus software. Unfortunately, after  running the model, the pore water pressure is didn't raise up. I don't know if any kind of subroutines I must use or anything else. I'm in the final step of  my thesis analysisand I really need your helps.

Deformation gradients and atomistic simulations

Submitted by Biswajit Banerjee on

I came upon a recent paper called "Deformation gradients for continuum mechanical analysis of atomistic simulations" by Jonathan A. Zimmerman , Douglas J. Bammann,  and Huajian Gao, International Journal of Solids and Structures 46 (2009) 238–253 where the authors conclude with
