Derivation of maximum normal stress at principal plane
To find the maximum value of normal stress at some angle, we have to differentiate the normal stress transformation equation, (which we derived in the previous article) with respect to dθ.
Principal Plane :
It is the plane at which normal stress attains the maximum value.
Below is the derivation of maximum normal stress at principal plane.
