Consider the following stress state imposed on a material:
90 50 0
𝜎 = [50 −20 0 MPa.
0 0 14]
If the material responds elastically with a volumetric strain 𝛥 = 3.5 × 10−4, what is its bulk modulus?
(A) 150 GPa (B) 350 GPa
(C) 200 GPa (D) 400 GPa
Bulk modulus = hydrostatic stress/ volumetric strain = mean stress/volumetric strain Mean stress = (σx+σy+σz)/3 (90-20+140)/3 = 70 GPa Bulk modulus = (70*106)/(3.5*10-4)= 200GPa
Bulk modulus = hydrostatic stress/ volumetric strain = mean stress/volumetric strain
Mean stress = (σx+σy+σz)/3
(90-20+140)/3 = 70 GPa
Bulk modulus = (70*106)/(3.5*10-4)= 200GPa
