Moment Of Inertia Of Corrugated Sheets

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.

Moment of inertia of corrugated sheets.

Used to sandwich the corrugated core sheet. This type of corrugation pattern is formed using circular arcs and straight. To reduce computational effort of finite element fe calculations a corrugated sheet is replaced with an orthotropic plate. Bending and torsional rigidities.
