Question: hydrostatic tension and volume change 9 points the hydrostatic tension...

Question details

Hydrostatic tension and volume change, 9 Points) The hydrostatic tension changes the volume of materials with the following equation 0 where T is the hydrostatic tension, B is the bulk modulus, V is the amount of volume change and Vo is the initial volume. For a given stress state, (a) Find T from the given stress state below (4 points), and (b) calculate the percent volume change,-x100 (%) (3 Point). (c) Does the material volume expand or shrink? (2 Points) Here, the bulk modulus is 10 GPa (GPa-10° Pa). The stress state is the following 0 20 5 40 5-10-4 | (MPa) 40 o,-| 20
