What does the virgin compression curve indicate?
💡 Hint: Where do we see heavy compression taking place on the graph?
Hysteresis loops are formed during which processes?
💡 Hint: Consider if these loops appear when there's a difference in stress paths.

Challenge Problems
Push your limits with advanced challenges
A load is applied to a soil sample which undergoes a certain amount of compression. If the load is then removed, calculate how much strain remains in the soil given a known elastic modulus and previous void ratio.
💡 Hint: Break down the calculations into elastic and plastic components.
You have two soil samples; one follows a distinct compression curve while the other has similar parameters but shows hysteresis. Discuss the implications of these differences on sub-grade performance when loaded.
💡 Hint: Compare and contrast their compressibility behavior as structural foundations.
