I am trying to understand the effect of Geocells on Infill material's Young's Modulus. For example if a material as a modulus of 70MPa, how much it will be if was placed in Geocells. (the modulus of the composite of material {infill + Geocells}) ?
Thank you for your answer. This is may be true for bearing capacity, but one can not assume that this will be the case for Young's Modulus of the material. Material modulus is not always a function of bearing capacity, so a 10 time increase in bearing capacity may not lead to an equivalent increase in Young's Modulus.
Dear Mohamed,
The modulus for th einfill is the same as the modulus determined from any test (though it may differ from one test to another)..
I believe you mean the eqiuvalent modulus for the composite, the cell and the soil.
No one can give you an answer to this question because the composite equivalent modulus is both cell geometry and state of stress dependent.
It will therefore varry from a problem to another and from point to another in the same problem.
A rough overall equivalent modulus can be obtained for a given problem by back-calculating it from experimental records for that particular problem.
Kind regards,
Hesham Elshazly
I'm agree with Hesham Elshazly. An equivalent modulus of elasticity of the composite can be obtained experimentally or as an average value of the two composite materials.
