Metamaterials with stiffness tunability have demonstrated great potential in mechanical systems that operate in variable environments. Real-time stiffness visualization, which translates the stiffness ...

Bolted joints are among the most common structural elements in precision machinery. They are used because they are strong, serviceable and reliable. Yet, despite their prevalence, the moment stiffness ...

Simulating these assemblies using traditional finite-element techniques, however, takes a great deal of time and experience. "And when a design model contains several pins, such as a scissors lift, ...
