A numerical scheme grounded on the Boundary Element Method expressed in the
Frequency Domain is proposed to perform Nonsmooth Modal Analysis of one-dimensional …

This contribution proposes a numerical procedure capable of performing nonsmooth modal
analysis (mode shapes and corresponding frequencies) of the autonomous wave equation …

This dissertation proposes a methodology to perform nonsmooth modal analysis of a
simplified prototype system in the form of a finite elastic bar whose motion is unilaterally …

Finite elements in space with time-stepping numerical schemes, even though versatile, face
theoretical and numerical difficulties when dealing with unilateral contact conditions. In most …

In the framework of non-smooth modal analysis (mode shapes and corresponding
frequencies) of structural systems, earlier investigations by Carlos Yoong allowed to spot …

In structural dynamics, autonomous conservative systems most commonly exhibit
continuous families of periodic orbits in the phase space, usually known as modes of …

A normal mode of vibration, characterized by a natural frequency and a modal shape, is a
widely understood concept in linear dynamics. This notion has been extended to the context …
