The humble rectangular block shown below is under uniaxial tension. Note the dimensions of the block. The applied normal traction on faces with normals parallel to x' is 75 MPa. The Young's modulus of the material is 200 GPa and the Poisson ratio is 0.3. We'll assume that plane stress conditions apply.

 
We'll employ friendly redAnTS to solve this problem using FEA. We'll plot various components of stress and strain for the block and compare them with theory.
