Autobiography:
Since 1997, and after obtained my Mechanical Engineering degree, I have been involved in the field of numerical simulation, directly dealing and programming within the Finite Element Method (FEM).
I have completed my PhD studies in University of Porto in 2004, in the subject of finite element design, formulation and implementation for general structural applications and metal forming simulations. My MSc degree, from University of Porto, Portugal, was obtained in 1999 in the field of numerical simulation of shell structures, including dynamic effects and instabilities.
After that, in 2000, I started my career at University of Aveiro, Department of Mechanical Engineering, where I am integrated as a faculty member of TEMA Research Unity.
Following my specialization in plate and shell structures, my main core of research is the study and improvement of the simulation aspects related to plastic forming processes, namely sheet, bulk and hydro-driven forming processes. Developments in these areas focus on the formulation and implementation of innovative membrane, shell, solid and solid-shell finite elements, integrated into in-house finite element programs in FORTRAN language as well as into commercial FEM packages, such as Abaqus, MSC-Marc and, more recently, LS-Dyna.
Additionally, my work is intimately related to the study and implementation of anisotropic constitutive models for metallic alloys, as well as the development and implementation of contact algorithms strategies suitable for general forming applications.
Currently I am responsible for a research project related to the prediction, by means of numerical simulation, of the springback and wrinkles onset in metallic alloys products obtained by stamping and tubular hydroforming, and including optimization procedures. I am also involved in two research projects in the domain of hydroforming of tailor-welded tubes and metal cutting processes.
More recently my research fields have broadened, now encompassing structural instability advanced problems (aeronautic integrally stiffened structural panels design and simulation) as well as studies in the field of impact, ballistics and light-weight armour development and simulation for defense applications.
Related to my teaching activity at the University of Aveiro, and counting the last decade, I have been involved in the following chairs (in chronological order): “Industrial Production”, “Technical Drawing”, “Mechanical Engineering Drawing”, “Solid Mechanics”, “Structural Mechanics”, “Applied Mechanics I”, “Applied Mechanics II”, “Computational Mechanics”, “Simulation of Numerical Processes” and “Plates and Shells”.
Since 2008 I am a member of the research group GRIDS, integrated in the Department of Mechanical Engineering (University of Aveiro), where I am currently the responsible for the DiPFORM division (Division of Plastic Forming). Specifically dealing with this subject, I have the honour to intensively collaborate with a team of about 15 people, including full time doctorates, PhD and MSc scholars and under-graduate students.
Additionally, since 2006 I am the Director of the Integrated Master Course in Mechanical Engineering of the University of Aveiro.
