Dr Ludovic Renson has received the 2017 Doak Award for his review paper on the “numerical computation of nonlinear normal modes in mechanical engineering”. The concept of nonlinear normal modes (NNMs) plays an important role in the analysis of the dynamic behaviour of nonlinear mechanical structures. The last decade witnessed the development of numerous numerical methods to calculate NNMs. Ludovic’s paper is the first to offer an overview of the developments carried out in this field and to perform a detailed and critical assessment of the different families of methods.
The Doak Award was established in 2011 to highlight the most successful paper in the Journal of Sound and Vibration each year. It is given for the paper which has the best combined record of downloads and citations. The award is made in the name of Professor Philip E. Doak, the first Editor-in-Chief of the Journal of Sound and Vibration. The award was presented at the ISMA conference held this September in Leuven, Belgium.
Dr. Renson is a Research Fellow working in the Department of Engineering Mathematics at the University of Bristol to develop tools and methodologies for testing nonlinear dynamic systems. His paper “numerical computation of nonlinear normal modes in mechanical engineering” can be read in full here.
