A sandy normally consolidated soils has N=15. What is the Eu (elastic modulus) of the soils in ksf?

A normally consolidated inorganic clay soils has Su=1000 psf. What is the Eu (elastic modulus ) of the soils in ksf?

An organic clayey silt has Su=400 psf. What is the Eu (elastic modulus )of the soils in ksf?

I looked at CERM over and over, I wound up reviewing Triaxial Test and Mohr's circle. But none of those provide me information on Modulus of Elasticity. I know

G=E/(1+v), but without v, I can't calculate E.

Standard Penetration Test correlates many properties, but again it doesn't seem relate to Modulus of Elasticity. At least CERM is not talking about it.

Please provide more help on this. Thanks. Are you a GEO guy? :wel

You can typical find this in a Geo book

Non-cohesive material Eu=50(N+15)

Cohesive cohesive=400Su

Semi-cohesive with high organics=100Su

Blu thanks. I will keep it in my safe blanket.
