Derivation of maximum normal stress at principal plane

Sunday, November 20, 2011 19:27 No Comments

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 […]
