Abstract EN

In this study the basic engineering principles, goals, and constraints are all combined with fuzzy methodology and applied to optimally design sandwich panel circular plate roofs for large vessels loaded statically and dynamically.

These panels are made up of two stiff, strong veneer skins separated by vertical and peripheral stiffener plates.

Advantages are high strength, lightweight, and sustainability.

In the present approach, first the goals and constraints of the end user are identified and expressed as decision variables which are formulated using the engineering variables for materials, geometry, and function.

Then same consistent fuzzy satisfaction functions are formed over the desired ranges to suit the customer's desires.

The risk of extreme dynamic loadings exciting resonance is studied by natural frequency and mode analysis by FEM and analytical models.

The results show the most critical locations and give guidelines for innovative remedies of the concept before detailed FEM analyses to finalize the design.
