Searching for a postdoctoral position in biomaterials

Submitted by Anna Dolgran on

Dear imechanicans,

I am seeking for a postdoctoral position in the field of biomaterials. I am interested in the mechanical behaviour of natural systems and the development of new materials. I just finished my PhD on the mechanics of crotch and would like to continue my study in the field of biomechanics/biomaterials. I am highly motivated and well organized.

I am looking forward to hearing from you!

How to derive from poroelastic 3D equations to 1D Terzaghi equation?

Submitted by Xiaogai Li on
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

how element quality will affect the accuracy of results

Submitted by sagar_009 on

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

Submitted by Sol21 on

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.
