Thank you so much for your kind help.

Sorry for the late response.

You can use known relations between shear modulus G defined with direct shear test with modulus of elasticity E and bulk modulus K from theory of elasticity

Dear Dr Jovanovski,

I would like to read the paper. Could you sent it to me. I will appreciate that very much.

Thanks

Hayder
