N2 - Auxetic and conventional mechanical materials can be combined to program the shape morphing behavior of structures. We proposed a configuration of mechanical metamaterial unit cells shaped like four-leaved rose curves. These rose unit cells can have a wide range of positive and negative Poisson's ratios governed by a single control parameter. With the rose unit cells, we implemented a programmable design of structural deformation under loading. Two geometric parameters are engaged to optimize the shape morphing effect. We fabricated several programmable metamaterial samples by SLA 3D printing, performed tensile loading tests, and got a good agreement between the numerical and experimental results.
