Approximating piecewise nonlinearities in dynamic systems with sigmoid functions: advantages and limitations

HIGHLIGHTS

  • who: Cristiano Martinelli from the Department of Naval Architecture, Ocean and Marine Engineering, University of Strathclyde, Montrose Street, Glasgow , LZ, Scotland, United Kingdom have published the Article: Approximating piecewise nonlinearities in dynamic systems with sigmoid functions: advantages and limitations, in the Journal: (JOURNAL)
  • what: To investigate this problem, the authors focus the attention on non-chaotic attractors generated by a nonlinear two-DOF mechanical system with a soft free-play gap. The novelty of the paper is two-fold: first, it aims to study the effect of smoothing functions on the mechanical response of a . . .
