How to derive from poroelastic 3D equations to 1D Terzaghi equation?
Hi!
In the terzaghi equation, there is a constant M (some books call is elastic oedemetric coefficient).
Since the terzaghi equation is a special case for the general 3D biot equations under oedemetric test
boundary conditions, does any book or material explain the derivation?
If I want to mode the terzaghi problem using 3D model in FE program, the M is known, then how to get the
Ludwig Boltzmann: the man who trusted atom(Chinese version)
One of the book may help us understand why Boltzmann can have so many new ideas (atom theory, statics mechanics and so on)
how element quality will affect the accuracy of results
hi all,
I want to know how the element quality is decided.
For example: for warpage of elment if allowable limit is max 15deg, what will happen if it exceeds 30 deg.
On what basis this limit is calculated.
Like this for the other quality parameters also.
plz help

Choice of the analysis for stress relaxation of PBT in real time scale
I am trying to simulate the long term behaviour of the PBT (polybutyelene terephtalate) thermoplastic.
The mesh and initial stress distribution data (after ejection from the mold) were exported from Moldflow commercial program as Abaqus input (*inp) file. By default, I have already got a fist step of the simulation (linear elastic properties of polymer). What I actually need now is to simulate the long-term performance (for example in the interval of hundreds or thousands hours). It means that the real time scale is of the utmost importance for the analysis.
Good substitute for cowper-symonds in Abaqus
Hi all,
I want to capture strain-rate behaviour of materials but unfortunately abaqus does not have Cowper-Symonds which is a widely used (simple) model. However johnson-cook is to complicate for me as not much details are available in literature as i am modeling bio-materials. Is there any good substitute for Cowper-Symonds models in abaqus. Thanks.
