This is extremely true for systems with moving parts and loose fixtures which show piecewise stiffness behaviours. Nevertheless, the numerical solution of systems with ideal piecewise mathematical characteristics is associated with time-consuming procedures and a high computational burden. Smoothing functions can conveniently simplify the mathematical form of such systems, but little research has been carried out to evaluate their effect on the mechanical response of multi-degree-of-freedom systems. 2023-04-17T03:24:13Z 2023-04-17T03:24:13Z 2023 Book https://link.springer.com/article/10.1007/s11071-023-08293-1 https://dlib.phenikaa-uni.edu.vn/handle/PNK/7980 en application/pdf Springer |
