Flexure bearings under plastic deformation for mechanical energy absorption

A flexure bearing is a mechanical component designed to enable controlled flexing or deformation, resulting in low-friction movement. It typically consists of thin, flexible materials and is used in precise applications, such as optical systems, robotics, and aerospace, for motion control. Due to th...
