IUTAM Symposium on Nonlinear dynamics for design of mechanical systems across different length/time scales

Nonlinear phenomena arise in a variety of mechanical and physical systems. Also, the experimental analyses for nonlinear dynamics, together with theoretical analyses, confirm only the reliability of the theoretical results, but also deliver meaningful hints on realizing high-performance machines, which exhibit features of high-accuracy, high-speed, high-flexibility, high-reliability and so on. In fact, the positive utilization of resonant vibrations and their nonlinear characteristics can be found in various devices such as auto-parametric vibration absorber, gyroscopic damper, ultra-sonic vibrational machine tool, atomic force microscope, ultrasensitive mass sensor, and so on, in the fields across diverse length scales, i.e., from macroscopic applications to micro/nanoscopic ones. Reflecting these situations, we believe that it is indeed timely and valuable to hold an IUTAM symposium on “Nonlinear dynamics for design of mechanical systems across different length/time scales.” The Symposium, while shedding light onto state-of-the art knowledge and advancements, is eminently expected to pave the way towards future directions and perspectives in the field. Share of the knowledge on experimental approaches to nonlinear dynamics by extensive discussions and exchange of ideas in the symposium may help to devise novel comprehensive methods to understand nonlinear phenomena much more deeply and lead to paradigm shifts in mechanical system design towards next-generation design by positive exploitation of nonlinear phenomena.
