If the stress state of a material is MPa and E = 25 GPa, what is the strain? Assume first that the material is compressible

If the stress state of a material is [40 30 10] O = 30 60 L10 201

MPa and E = 25 GPa, what is the strain? Assume first that the material is compressible (v = 0.3), then that it is incompressible (v = 0.5).

[40 30 10] O = 30 60 L10 201
