From: Increasing design flexibility by manually adapting the solution space for crashworthiness
Representation of the two-dimensional design space: the light grey area represents the design space, the white area — delimited by the maximum deceleration, the order of deformation and the minimum energy absorption constraints — represents the space of feasible solutions, and the area inside the rectangle is the area of feasible and independent solutions. The dashed line corresponding to \(F_{2}=300\text{ kN}\) represents the desired design points the developers want to include in the solution space
