stress as initial condition
stress as initial condition
(OP)
Hi, I am analysing a model of pile structure. I want to define the weight of soil as initial condition and then apply the loads. How can I define stress as initial condition? Do you know any example?

RE: stress as initial condition
If you want consider the weight, then just activate the Define loads>>Apply>>Structural>>Inertia>>gragity. Why do u need stress as initial condition?
RE: stress as initial condition
One solution is define the weight in first load case and external loads in second and by subtracting I will have the deformation only cause by external loads. Another method usual method in geomechanic is defining the stress as the initial condition. As you know in material like soil (because of the internal friction) the strength of material (for example Drucker-Prager material model) is related to normal stress and we have to consider the effect of weight on stresses during analysing
RE: stress as initial condition
Do you use the Drucker-Prager material model?
You can define soil behaviour with this theorie.
