Introduction

We are hiring! We have an open position for a PhD candidate in the exciting area of multiscale and multiphysics modelling of sustainable fibrous composites with additional focus on uncertainty quantification and machine learning.

Job Description

• The context: Natural fiber reinforced materials are increasingly used as environmentally friendly alternatives for composite materials due to the sustainability and circularity of the natural fibers (e.g. hemp flex bamboo). Natural fiber reinforced composites have applications in different engineering fields including construction (used for insulation and load bearing members) automotive (used for interior components) and consumer products (e.g. in sporting products). The natural fibers used in these composites are sensitive to moisture-induced and chemical degradation. Moreover they exhibit a high degree of variability in their composition and microstructure which results in variability in their mechanical thermal and diffusion properties. Therefore predictive modeling of the performance of these composites is a multidisciplinary problem centered around computational mechanics and engineering potentially involving (i) multiphysics problems (ii) multiscale methods (iii) uncertainty quantification and (iv) machine learning.
• The project will focus on one or a combination of the following focus areas tailored to the candidates expertise and interests:
  • Developing numerical models for the coupled mechanical-diffusive(-thermal-chemical) behavior of fiber-reinforced composites at the micro/meso-scale. These models will incorporate uncertainty via stochastic inputs such as random field representations of spatially varying material properties. The resulting response will be analyzed using techniques such as Monte Carlo simulations.
  • Identifying the variability of the model parameters using Bayesian inference.
  • Quantifying the impact of microscale uncertainties on macroscale material performance through stochastic homogenization and uncertainty propagation methods including Monte Carlo and Gaussian Process-based approaches.
  • o Integrating machine learning techniques to replace computationally expensive simulations and enable faster predictions while preserving uncertainty information.
• The successful candidate will work in the chair of Applied Mechanics Department of the Built Environment under the supervision of dr. Emanuela Bosco and dr. Payam Poorsolhjouy as well as dr. Lars Beex (University of Luxembourg) . The chair of Applied Mechanics is responsible for education and research in the field of mechanics working on multiscale multi-physics and optimization problems related to the built environment. The chair is a member of the Graduate School of Engineering Mechanics Netherlands. This graduate school offers PhD students an advanced training program in engineering mechanics the core of which is a joint series of advanced graduate courses closely connected to state-of-the-art research themes.
• The successful candidate will interact closely with other PhD students (numerical and experimental) who work on other aspects of the mechanical and multiphysics behavior of heterogeneous materials.

Job Requirements

• A talented motivated and enthusiastic researcher. Analytical skills initiative and creativity are highly desired.
• A MSc-degree in Mechanical Engineering Civil Engineering Computational Mechanics Mathematical Engineering or equivalent is required.
• A strong background in mechanics of materials and multi-scale and multi-physics methods is highly desired.
• Additional expertise in uncertainty quantification and/or machine learning techniques is advantageous.
• Interest to work in an interdisciplinary project that incorporates different fields of expertise including analytical/computational frameworks uncertainty quantification and machine learnig to solve problems with significant social and industrial impact is beneficial.
• Excellent oral and writing skills in English are required (C1 level).
