Abstract
The invention relates to a structural sheet formed with cup-shaped projections in which the sidewalls are formed by a sigmoidal line of revolution to provide for more uniform distribution of stress in the structural sheet. There is also provided a novel two-component structural panel which incorporates the advantages of such a structural element to eliminate depressions in the outer panel member which would present 'read through' problems.
