Prioritized multi-objective optimization of a sandwich panel

Abstract : This report is intended to demonstrate numerically the potential of the prioritized multi-objective optimization approach by applying it to the sizing of a sandwich panel with respect to mechanical criteria: mass, critical failure forces under bending load (1st and 2nd modes), and blast mitigation measured by the core energy absorption, deflection, or both. Several objective functions are defined based on analytical models. Four numerical test-cases are documented. In each test-case, the Pareto front associated with two constrained criteria only, including mass, is first established; then, the design is improved by accounting for one or two additional criteria by the construction of a continuum of Nash equilibria tangent to the front in function space at the starting point.
