In a method for manufacturing prestressed shells having tunable bistability, in order to determine the appropriate prestress to be applied to the bistable structure/shell, it provides: clamping a shell by applying a predetermined curvature on a portion of its edge; defining a discrete shell model dependent on a small number of configuration parameters q_i, (i<5), by projecting the non-linear shell model of Marguerre-von Kármán onto an appropriate finite dimensional space so that the projection does not significantly alter the strain elastic energy; tracing the stability maps in the space of the design parameters by minimizing the discrete representation of the strain elastic energy E(q_i;p_i) thus obtained; and choosing the design parameters providing the prestress needed to obtain the desired response in terms of project requirements.
