An isotropic sample of a material is subjected to a compressive stress of 230 MPa in the x direction. However, it is confined so that the sample cannot deform in the y and z directions. Data: Young’s modulus of the block E = 46 GPa Poisson ratio υ = ⅓ Height = 0.5 m Width = 0.5 m Length = 0.5 m Calculate these stresses in the y- and z-directions (in MPa to 2 decimal places) Calculate the strain in the x direction. (% to 2 decimal places) DO NOT INCLUDE UNITS.

X-direction Strain (%)

Y-direction (MPa)

Z-direction (MPa)

Solutions

Expert Solution

Strain in x direction = -0. 3333%

Stress in Y and Z direction are same and equal to 115 MPa. And compressive in nature.
