This type of corrugation pattern is formed using circular arcs and straight.
The moment of inertia or more accurately the second moment of area is defined as the integral over the area of a 2d shape of the squared distance from an axis.
To reduce computational effort of finite element fe calculations a corrugated sheet is replaced with an orthotropic plate.

The following links are to calculators which will calculate the section area moment of inertia properties of common shapes.
Each calculator is associated with web pageor on page equations for calculating the sectional properties.
However the orthotropic.
It should not be confused with the second moment of area which is used in beam calculations.
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.
