This study investigates friction effect on postbuckling behavior of bi-constrained strips. We develop a frictional large deformation model to study the mechanical response of bi-walled strips subjected to axial compression. The Euler-Bernoulli beam t

Post-buckling analysis of micro-composite films (MCF) has been extensively investigated in recent years. However, the literature of composite elements at micro/nanoscale has been mainly focused on buckling response without lateral confinements. This

Microdevices, consisting of axially loaded elements at the microscale, are typically designed as bilaterally constrained microbeams with non-prismatic shape configurations. The literature has been mainly focused on uniform microbeams. Here we report

This paper develops a static and dynamic large deformation model to investigate the post-buckling response of slender beams constrained by movable and flexible bilateral confinements. A novel discretization algorithm is proposed to convert the irregu

Buckling instability refers to a significant limit on the structures with I-section members, which causes severe decreasing of critical buckling load. Many mechanisms and techniques have been developed to increase the loading capacity of I-section st

Post-buckling phenomenon has been performing advantages in many applications. In particular, buckling snap-through of slender beams under lateral constraints is of great research interest since low-rate and low-frequency excitations can be transforme

Bistable and multistable structures have shown great usefulness in many applications such as MEMS actuation and energy harvesting. Bistability of structures can be achieved through buckling. Confining a buckled beam between two lateral constraints al
