Un muelle helicoidal estrechamente enrollado está cargado por una fuerza de compresión. The spring has middle diameter D, wire diameter d, and it consists of i turns. The total length of the spring is L. Determine the total deflection of the spring for the member model and one‑turn deflection for the solid model.
Un oscilador simple consta de una masa m (considerada solo en la dirección x) y un muelle lineal de rigidez k. The mass is embedded on a surface with Coulomb friction and is loaded by constant-in-time axial and transverse forces.
El objetivo de este ejemplo es demostrar un proceso irreversible causado por la fricción. After the loading and unloading, the end-point is in a different position than where it was at the beginning. Determine the movement of the node in the X direction.
