Description:

2D stress transformation and Mohr's circle for plane stress.

What can be modified:

• value of normal stress σ_x and σ_z and shear stress τ_zx,
• value of angle α between original coordinate system xz and rotated coordinate system x'z'.

Notice:

• stress states mutually rotated by 180° equals each other,
• rotation of maximal normal stress σ and rotation of maximal shear stress τ differ by 45°,
• for principal directions (directions where one normal stress σ is maximal on the other is minimal), shear stress τ always vanishes,
• for direction of maximal shear stress τ, both normal stresses σ equal each other and have value equal to the center of the circle.
