Viscous boundary for half model

Chua Shin Ying — Thu, 26 Mar 2020 13:28:36 GMT

Hi,

I am trying to model a half model in PLAXIS 3D in order to reduce computational time.

The context here is a dynamic problem, with an moving train load in a under ground tunnel.

So, I have set the Xmin boundary condition to be normally fixed and not applying viscous boundary. This is because when i apply viscous boundary in the Xmin direction, it moves and that is not what I want.

Is there any way in which I can model the viscous boundary but still not maintaining the fixity in the Xmin direction?

Thank you.

Tunnel interfaces (Soil-stc

Hi,

May I ask, in the modelling of soil-structure interaction between tunnel lining and soil, does the Rinter in PLAXIS 3D works for linear elastic soil model?

This is because there is no friction angle and cohesion input for linear elastic soil model.

Thank you!

PLAXIS 3D Moving Load Function

Chua Shin Ying — Mon, 17 Feb 2020 16:39:06 GMT

Hi all,

May I ask a question regarding the theory behind the moving loads function in PLAXIS 3D?

I understand that users can assignment Movement to point loads with a linear, harmonic or table based signal specifying an initial velocity, acceleration, or variation of the velocity through time. But, is there any underlying theory behind this logic?

Thanks!

Hi,

I have encountered a meshing problem. May I know if there are any ways to solve this problem?

Thank you!
