Hydraulic Stress

Hydraulic Stress

The stress is the fluid pressure p on the object, which, as you will see in Chapter 15, is a force per unit area. The strain is , where V is the original volume of the specimen and is the absolute value of the change in volume. The corresponding modulus, with symbol B, is called the bulk modulus of the material. The object is said to be under hydraulic compression, and the pressure can be called the hydraulic stress. For this situation.
