Research Groups

  1. Mechanical System Dynamics

Development of numerical and experimental methodologies highlighting applications in three major topics. The first in the scope of modeling and analysis of dynamic systems with emphasis on non-linear dynamics and chaos, propagation of waves in mechanical structures and systems, control of vibrations, modeling, and uncertainty quantification. The second related to the identification in vibrations and acoustics, encompassing reverse issues based in adjustments of model (model updating) and Bayesian inference, as well as applications in the detection of structural damages. The third topic associated with modeling, simulation, and experimenting of intelligent structures subjected to dynamic loads, especially mechanical systems constituted of intelligent material (shape memory alloys and piezoelectric material) for the control of vibrations and collection of energy.

This research line is conducted by the Group of Systems Dynamics, whose members accredited in the PCMEC are:

  1. Energy and environment

The Laboratory of Energy and Environment (LEA) dedicates to develop applied and fundamental research in systems of energy conversion and associated environmental issues. The research topics concentrate in systems of wind, hydrokinetic, and water conversion, solar, thermal, and photovoltaic energy, internal combustion engine, gas turbine cycles, carbonation, hybrid systems of energy conversion, bio-PCMs, energy management, analysis of life cycle, sciences of the environment and sustainability. Fundamental aspects are explored in researches related to heat transference and thermodynamics, such as natural and mixed convection in surfaces or sealed cavities, combustion, and environmental flows.

This research line integrates the following professors accredited to the PCMEC:

  1. Fatigue, Fracture, and Materials

Development of theoretical, experimental and numerical researches related to the prediction of durability of components and structures subjected to cyclic loads. Highlights to investigations encompassing the following topics: fatigue in couplings under fretting conditions, fatigue in energy power cables, effect of multi-axis loads, contact surfaces wear, ductile fracture, damaged plasticity, structural reliability, and contour elements methods.

This research line has strong interaction with researchers in the area of materials, especially regarding applications involving the sourcing and characterization of metallic, ceramic, polymeric, composites, intelligent materials, and biomaterial. The applications involve sensors, fuel cells, automobile parts, and sustainable products.

The researches have been carried out in the context of a solid partnership with both national and international companies (Safran Aircraft Engines, TBE – Brazilian Power Transmission Companies, Taesa, Eletronorte, Galp) and universities of international excellence (Université Paris-Saclay, KU Leuven University, University of Parma, Durham University, Lulea University of Technology, University of Alberta, Higher Technical Institute of Lisbon). The works have a high level of internationalization also involving a number of dissertations supervised in the context of double degree system (cooperation).

The researches in Fatigue, Fracture, and Materials are conducted in the context of an infrastructure equipped with the best laboratories worldwide, including four machines for axial tests, two machines for axial-torsional tests, and other two machines for tests of fatigue by fretting and equipment of thermal analysis, chromatography, and spectroscopy. We also count with three gaps for fatigue testing in energy power cables – the only one available in the Southern hemisphere, in addition to two furnaces to perform fatigue tests at high temperatures, scanning electron microscope, and laser confocal microscopy.

This research line is conducted by the Group of Fatigue, Fracture, and Materials (GFFM), composed by the following professors, among which 80% are scholarship holders for research productivity in the scope of CNPq:

  1. Fluid Mechanics of Complex Flows

Theoretical, numerical and experimental researches developed in the area of Microhydrodynamics and Rheology of Fluids Complex. The most specific topics of interest of the group VORTEX are the following: microhydrodynamics and rheology of complex fluids involving active and passive particles in suspensions, dynamics of non-Newtonian fluids involving emulsions and colloidal systems in general, flows of granular material, fluctuations of speed and hydrodynamics dispersion in suspensions of sedimentation or shearing, stability of fluidized beds, and dynamics of blisters in complex fluids. The research developed by the group is highly interdisciplinary, a perspective in which VORTEX aims at developing systematic procedures to study phenomena in complex flows always seeking to analyze microstructural aspects in the microscopic response of flows and the consequent passing of the generated knowledge  to the industrial sector.

This research line is conducted by the Group of Fluid Mechanics of Complex Flows (VORTEX), whose members accredited to the PCMEC are:
