Project description

The main objective of my work is to refine and extend the model of failure of unidirectional composites under tensile loading, developed at Mines ParisTech. I want to include the influence of temperature, humidity, and porosity on the properties of the composite's matrix. These factors are especially significant in the long time scales. Experimental tests are going provide a solid physical basis for the modeling.

The model will be applied to studying carbon fiber pressure vessels. They are an important market for the composite industry. However, our incomplete understanding of the failure processes in composites prevents us from taking full advantage of their properties. New numerical models can help fill the gaps in our knowledge. I would like my work to be a part of that process.

Education

PhD researcher at MINES ParisTech (2017-present).

Erasmus Mundus Master Course, Computational Mechanics, Polytechnic University of Catalonia, Spain / University of Stuttgart, Germany / Tsinghua University, China (2014-2016).

B.Sc., Aerospace Engineering, Warsaw University of Technology, Poland (2010-2014).

Research interests

Numerical methods, finite element method, failure of composite materials, aerodynamics

Personal note

I like following the new developments in aeronautics and space technology. Since moving to France for the PhD, I enjoy discovering Paris on weekends. On holidays, I like to go for long mountain hikes.
