A deployable structure can significantly change its geometric shape by switching lattice
configurations. Using compliant mechanisms as the lattice units can prevent wear and …

Bistable beams with prebuckled sinusoidal shape are prominently constructed into
mechanical metamaterial unit cells with bi-and multi-stability. While the effects of boundary …

Curved beams with bistable and negative stiffness properties can be used to design multi-
stable metamaterials or honeycomb structures. Consequently, the deformation patterns and …

We derive the snap-through solution and the governing snapping force equations for an
arbitrarily preshaped beam deflected under a mid-length lateral point force. The exact …

With unique mechanical properties, negative stiffness (NS) structures have presented
significant advantages in energy absorption. In recent years, NS structures consisting of …

A small bistable mechanism with a strong robustness to external disturbances is eagerly
desired in many practical applications. The difference between the switching forces in …

We study the dissipative bistable Duffing oscillator with equal energy wells and observe
fractal patterns in the parameter space of driving frequency, forcing amplitude, and damping …

Pre-shaped microbeams, curved or inclined, are widely used in MEMS for their interesting
stiffness properties. These mechanisms allow a wide range of positive and negative stiffness …

A tunable symmetric bistable micro-machined mechanism with monolithic structure is
presented. The mechanism consists of two sets of pre-shaped beams of similar properties …

Conventional crash absorbers dissipate kinetic energy of impacts into plastic irreversible
deformation, needing an immediate replacement to restore safety of the structure, highly …
