Contact-aided compliant cellular mechanisms are cellular structures designed with contact mechanisms integrated into
each cell to provide stress relief. This article addresses compliant cellular structures having curved walls and internal
contact mechanisms. The use of curved walls in cellular structures tends to improve their performance in terms of global
strain capability and is beneficial for fabrication. In some cells, the addition of contact mechanisms results in stress relief,
allowing the cells to be stretched farther than they could without contact. The cellular structures with curved walls are
modeled, and finite element analysis is used to calculate the maximum global strains for comparable noncontact and
contact-aided cells. An optimization procedure is performed to find the cell geometries that result in the highest global
strains. Strains of up to 32.4% and 19.7% are predicted for the optimized curved noncontact and contact-aided cells,
respectively. Additionally, a comparison of curved and noncurved, noncontact and contact-aided cells shows that the
addition of curved walls results in a significantly greater improvement in global strains than that gained by adding a contact
mechanism. Mesoscale contact-aided compliant cellular mechanism designs are fabricated via the lost mold–rapid
infiltration forming process and are tested using a custom-designed test rig.
