In the current international context in which the pandemic has dealt a severe blow, several questions arise in relation to the future of global governance (GG) and the role that emerging countries such as the BRICS (Brazil, Russia, India, China and South Africa) will play in it. First of all, governance itself has been shown to have several deficits and has been radically affected. Furthermore, it is questionable as to what challenges the BRICS will face internally in the future, especially at the end of the pandemic, and whether they will give rise to a new global order. For this reason, in this paper, we analyse the meaning of "power transition" and "hegemony", and we also try to give a reading of some practices carried out by the BRICS in the fields of climate change governance, the inclusion of civil society and the role that these countries play in international institutions such as the United Nations and in forums such as the G20. Having noted the limits in these areas, our idea is that today, more than ever, the need to have a global approach to development is increasingly necessary. Even the BRICS, which in reality do not seem willing to overturn the current international context, will be called upon to play an important role in the future of GG and international relations, specifically in contributing to carrying forward this global development approach.

The present paper reports the results obtained by a methodology of damage detection in which combined EMA and FEM data are used to localise the damage on mechanical components. The utilized method uses the eigenvalues and eigenvectors obtained from FE modelling, compared with the eigenvalues obtained experimentally on damaged specimens. The method assumes a linear behaviour of the materials. Firstly it is applied to rectangular plates in order to test its reliability in discovering the damage located on very simply shaped specimens that are made of homogeneous and isotropic material. The methodology was subsequently applied to mechanical components of complex shape, allowing the location of the damage to be accurately identified.
