Plane stress transformation

Plane stress transformation with explicit inputs, units and reproducible calculations.

Inputs

• Normal stress x (MPa)
• Normal stress y (MPa)
• Shear stress xy (MPa)
• Counterclockwise axis rotation (degrees)

Assumptions and limitations

Plane stress tensor rotation only, tensile normal stress positive; positive shear is the xy tensor component. No failure criterion, material law or design check.
