void ratio การใช้

Finally, the relationship between void ratio and effective stress is not independent of time, again proven by experimental results.
The data is usually arranged on a semilog plot of the effective stress ( frequently represented as ?'vc ) versus the void ratio.
Mud and snow ( M & S ) tires are designed with higher void ratios to channel away rain and mud, while providing better gripping performance.
This is due to the non-linearity of the relationship between void ratio and effective stress, although for small stress increments assumption 7 is reasonable.
Using a load increment ratio of 1 / 2 provides a sufficient number of data points to describe the relationship between void ratio and effective stress for a soil.
