Question 1.
Define shear modulus.
Show hintHide hint
Remember that G indicates soil resistance.
Question 2.
What happens to shear modulus when cyclic strain increases?
Show hintHide hint
Consider what occurs during repeated stress applications.
3Question 3.
What does shear modulus represent?
- Stiffness of soil
- Weight of soil
- Color of soil
Show hintHide hint
Think about the role of G in your studies.
4Question 4.
True or False: The shear modulus increases with cyclic strain.
- True
- False
Show hintHide hint
Remember how soil reacts to repeated stress.
Question 5.
A saturated loose sand experiences cyclic loading leading to a drop in shear modulus from 40 MPa to 15 MPa. What does this indicate about its stability during an earthquake?
Show hintHide hint
Reflect on how soil behavior changes under stress!
Question 6.
Using dynamic modulus curves, how might one predict the shear modulus of a soil after a certain strain level of 5%?
