The critical shear load of corrugated sheets. Also a higher order shear plate theory was considered expressions for the moment of inertia per unit length of single sheets with arc and tangent type corrugation have been given by blodgett 9 and wolford 10. The mass moment of inertia is often also known as the rotational inertia and sometimes as the angular mass. I moment of inertia of corrugated shape in 4 in.
