                      Mohr's Circle


• It is a graphical representation of Biaxial (2D) state of stress.

• It is a stress circle which is used to determine the normal stress & shear

stress on any oblique plane.

• Mohr's circle is also used to determine the principal stresses and principal

planes location.

• With the help of Mohr's circle, in combined state of stress condition, we

can determine principal stresses and maximum shear stresses.

Sign convention used in Mohr's circle:-

1. On X-axis, we represents normal stress & on Y-axis we represents shear stress.
