Torsion refers to the twisting or rotating force that can be applied to an object. In the context of research, torsion typically refers to the study of the behavior of materials or structures under twisting forces. This research area is important in fields such as engineering, materials science, and physics, as it helps to understand how materials deform, fracture, or fail under torsional stress. Researchers in this area may focus on developing models, simulations, and experimental methods to study torsion and its effects on different materials and structures.
