Dear Colleagues,

Hope you and your loved ones are staying safe and well in this difficult time.

PhD Position in geotechnical earthquake engineering

A postdoctoral associate position is available in Dr. Baoxing Xu’s group in the Department of Mechanical and Aerospace Engineering at the University of Virginia.

The successful candidate will work on a project related to nanomechanics and thermal transport of materials and functional structures and their coupling with applications in the design and manufacturing of electronic devices and structures.

Safer batteries, more efficient gas-turbine engines and solar cells, all require better-engineered nanocomposite materials. There is a limitation though -- how to investigate the fracture mechanics of these materials? Machine learning can help us overcome this limitation.

Nowadays, titanium and its alloys are widely utilized in various industrial parts in such areas as the petrochemical, medical, and automotive industries; However, due to structural considerations, the application is problematic in cases of joining. Ti 4Al 2V is a new type of titanium alloy, that in point of the structure is near to the α-series, which have many applications in critical conditions (moisture, steam, temperature, etc.).

PhD in Data-driven modelling of non-linear heterogenous materials

We are looking for an enthusiastic candidate with a sound background in micromechanics/solid mechanics, and interest in data-driven multiscale modelling of heterogeneous materials to work on a project 'Heterogeneous Materials in Extreme Environments' within the Centre for Doctoral Training HetSys at the University of Warwick (see https://warwick.ac.uk/fac/sci/hetsys/).

Entry requirements

Description:

The goal of this project is to investigate the multi-scale behaviour of clay rocks, going from microscopic to macroscopic scale, with application to underground drilling. The research will be based on multi-scale approach and numerical method allowing to model microstructure media in a double-scale framework (FEMxFEM). Please, see the full description in the attached file here below.

Theory of physical aging from polymer science is, for the first time, introduced to understand ACL injury and its prevention. By analogy to physical aging of amorphous polymer materials, we think physical aging of two bundles of ACL will largely increase risk of ACL injury. Besides, physical aging will also build a heterogeneous stress and strain in ACL due to its natural anatomic structure, which is a large risk for athletes. The specific designed prevention programs for ACL injury such as plyometrics, strengthening and other neuromuscular training exercises [1] are believed to erase physical aging of ACL. ACL with less physical aging is less likely to get injured in sport activities. In this article, a virtual physical aging simulation is built to validate current hypothesis. Erasing physical aging of ACL may provide an accurate and quantitative way to prevent ACL injury.

Abstract: Advanced machine learning methods could be useful to obtain novel insights into some challenging nanomechanical problems. In this work, we employed artificial neural networks to predict the fracture stress of defective graphene samples. First, shallow neural networks were used to predict the fracture stress, which depends on the temperature, vacancy concentration, strain rate, and loading direction.

In this paper, we formulate a theory for the coupling of accretion mechanics and thermoelasticity. We present an analytical formulation of the thermoelastic accretion of an infinite cylinder and of a two-dimensional block.
