I have a postdoc position available immediately in my research group (https://engineering.rowan.edu/dehub/). The position offers very competitive salary and it relates to an externally funded project on a cutting-edge topic of design optimization of metal parts for aerospace applications. The interested candidates must have a demonstrated capability to perform mechanical testing coupled with optical metrology and need to have good understanding of computational modeling. Please contact me directly as the position will be filled quickly.

I have an opening in my group for a 2-year postdoc position offering applicants an exciting opportunity to join my ERC-funded project “ALPS - AI-based Learning for Physical Simulation”.

Job description

You will be contributing to developing novel algorithms at the intersection of computational physics and machine learning for the automatic identification of symbolic models of physical systems starting from experimental data.

We are looking for a highly motivated candidate for a PhD position between École des Ponts ParisTech and University of Pavia, starting October 2024. The position is part of the EU-funded project MISCEA, an ambitious multidisciplinary Doctoral Training Network under the Horizon-Europe Marie Skłodowska-Curie Actions COFUND.

We demonstrate the feasibility of a scheme to obtain approximate weak solutions to (inviscid) Burgers equation in conservation and Hamilton-Jacobi form, treated as degenerate elliptic problems. We show different variants recover non-unique weak solutions as appropriate, and also specific constructive approaches to recover the corresponding entropy solutions.

By considering the frictional sliding of randomly distributed entanglements within the polymer network upon mechanical stretches, we develop a constitutive theory to describe the large stretch behaviors of highly entangled hydrogels.

Solidification phenomenon has been an integral part of the manufacturing processes of metals, where the quantification ofstochastic variations and manufacturing uncertainties is critically important. Accurate molecular dynamics (MD) simulations ofmetal solidification and the resulting properties require excessive computational expenses for probabilistic stochastic analyseswhere thousands of random realizations are necessary.

This paper provides a brief review on modeling of composite structures. Composite structures in this paper refer to any structure featuring anisotropy and heterogeneity, including but not limited to their traditional meaning of composite laminates made of unidirectional fiber-reinforced composites. Common methods used in modeling of composite structures, including the axiomatic method, the formal asymptotic method, and the variational asymptotic method, are illustrated in deriving the classical lamination theory for the composite laminated plates to see their commonalities and differences.
