Mercoledì 5 Marzo si terrà un seminario presso l’aula Grandori (Edificio 4) dalle ore 14:30 dal titolo “Probabilistic Entropies in Civil & Mechanical Engineering”.

Il seminario sarà tenuto dal Prof. Marcin Kaminski, full Professor in the Department of Structural Mechanics, Łódź University of Technology.

Abstract:

The main aim is to present the key ideas behind application of probabilistic entropy, and also probabilistic distance in civil and mechanical engineering problems subjected to various sources of uncertainty. A motivation for this research is to propose some alternative approach to the traditional moments-based methods available in probabilistic mechanics, where single universal uncertainty measure is determined instead of various statistics. This idea is implemented using Shannon entropy and further, an application of the probabilistic distance in structural reliability assessment is proposed, where Bhattacharyya distance is applied and contrasted with the traditional First Order Reliability Method (FORM). Numerical methods implemented for the solution of the static and dynamical problems are in turn – Monte-Carlo simulation, iterative generalized stochastic perturbation technique, and also semi-analytical approach. Their programming in the computer algebra system MAPLE is displayed. Engineering computations are delivered in conjunction with the Finite Element Method (FEM) systems ABAQUS and ROBOT. The test usage of the Artificial Neural Network (ANN) implemented in Python environment is also documented. The case studies under consideration include but are not restricted to (i) some MEMS device, (ii) dynamic response of the steel hall, (iii) wind-induced vibrations of the steel and hybrid skeletal structure, (iv) homogenization of some composite materials.

Speaker’s bio:

Prof. Marcin Kamiński has been a full professor in the Department of Structural Mechanics, Łódź University of Technology since 2015 and now He is the Head of the Discipline Civil Engineering, Geodesy & Transportation in the Faculty of Civil Engineering, Architecture & Environmental Engineering since 2019. He worked before in Division of Mechanics of Materials (1994-2009), was the Head of Department of Steel Structures (2010-2013); then He joined Department of Structural Mechanics as the Head of Division of Structural Reliability.

His main research includes the Stochastic Finite Element Method (and some other discrete stochastic numerical methods), numerical modeling of random composites including homogenization theory, reliability assessment and optimization of civil engineering structures, stochastic ageing processes, and also recently – an application of probabilistic entropy in engineering computations (in the framework of the research grant OPUS no. 2021/41/B/ST8/02432 sponsored by the National Science Center in Cracow, Poland).

He spent a postdoctoral study at Rice University in Houston, TX, USA, was a visiting professor at Leibniz-Institute of Polymer Research in Dresden, Germany, and also at Politecnico di Milano, Italy. He authored more than 200 research papers in various journals including International Journal for Numerical Methods in Engineering, Composite Structures, International Journal of Solids & Structures, and also Computers & Structures. He published two monographs: “Computational Mechanics of Composite Materials”, Springer, 2005, and also “The Stochastic Perturbation Method for Computational Mechanics”, Wiley, 2013. He serves as the associate editor in Mechanics Research Communications (by Elsevier, since 2013) and the member of editorial board in International Journal for Numerical Methods in Engineering (Wiley), Acta Mechanica (Springer), Computers & Structures (Elsevier), Journals of Composites Science, and also SCI (MDPI).

He was the recipient of the fellowships from Foundation for Polish Science (1996 & 1999), J. Argyris Award from ECCOMAS and Elsevier (2001), J.T. Oden Scholarship at The University of Texas (Austin, TX, USA, 2004), and also some Polish national or academic awards including Bronze Cross of Merit (1998), Silver Cross for the Longstanding Service (2017), Medal of Commission of Education (2022), and also very recently The Research Prize of Ministry of Education & Science in 2023. He has been recognized recently (since 2021) as the World’s Top 2% Scientists by Stanford University, CA, USA.
