Deformable connections in the context of research refer to the study of mechanical connections that have the ability to deform or change shape under various conditions. This field involves the investigation of how these connections respond to different forces, loads, and environmental factors, and how they can be optimized for specific applications. Deformable connections are commonly used in engineering and construction for joining different components or structures together while allowing for flexibility and movement. Researchers in this area may explore materials, design principles, and manufacturing techniques to improve the performance and durability of deformable connections in various industries.
