The aim is to design mechanical metamaterials that exhibit negative stiffness under various load types.
Designed structures with embedded pre-buckled and pre-twisted elements.
Considered tensile-based and compression-based models with varying wall thicknesses.
Analyzed the mechanical properties during loading for different displacement ranges.
Proposed structures exhibited repeated stress jumps and drops during loading.
Demonstrated negative stiffness in specific displacement ranges.
Indicated potential applications in multi-stage actuators and passive switches.
