Ph.D. and Post-doc opportunities in ‘Small-scale mechanics and advanced microstructural characterizations’ at Texas A&M

Dr. Kevin Xie's group at Texas A&M is planning to recruit two Ph.D. students and a postdoctoral research fellow starting 2018.


The overarching aim of the research projects is to understand mechanics of materials at nano- and sub-micron scales by applying advanced microstructural characterization techniques such as Cs-corrected STEM, TEM- based orientation mapping, EELS, and atom probe tomography. The details of the projects are as follows:

Dear all,


An image from our paper on micromechanical testing and modelling of heterogeneous materials (hydrated cement paste) has been selected by the editors to be on the cover of the special issue of the Materials journal dedicated to discrete modelling of concrete.

Self-Sealing Cementitious Materials by Using Water-Swelling Rubber Particles

Dear all,

Our group has recently published a paper on self-sealing of cementitious materials by using water-swelling rubber particles as admixtures. This is the first time that such an approach was developed to increase the water-tightness of cracks and therefore enhance the concrete durability.

The paper can be found at:

Computational modeling of tactoid dynamics in chromonic liquid crystals

Chiqun Zhang            Amit Acharya            Noel J. Walkington            Oleg D. Lavrentovich

Motivated by recent experiments, the isotropic-nematic phase transition in chromonic liquid crystals is studied. As temperature decreases, nematic nuclei nucleate, grow, and coalesce, giving rise to tactoid microstructures in an isotropic liquid. These tactoids produce topological defects at domain junctions (disclinations in the bulk or point defects on the surface). We simulate such tactoid equilibria and their coarsening dynamics with a model using degree of order, a variable length director, and an interfacial normal as state descriptors. We adopt Ericksen's work and introduce an augmented Oseen-Frank energy, with non-convexity in both interfacial energy and the dependence of the energy on the degree of order. A gradient flow dynamics of this energy does not succeed in reproducing some simple expected feature of tactoid dynamics. Therefore, a strategy is devised based on continuum kinematics and thermodynamics to represent such features. The model is used to predict tactoid nucleation, expansion, and coalescence during the process of phase transition. We reproduce observed behaviors in experiments and perform an experimentally testable parametric study of the effect of bulk elastic and tactoid interfacial energy parameters on the interaction of interfacial and bulk fields in the tactoids.

Theoretical and experimental constitutive modelling of soft materials at the nano scale: Cylindrical micellar filaments

We present theoretical and experimental descriptions of the elasticity of cylindrical micellar filaments using micro-mechanical and continuum theories, and Atomic Force Microscopy. Following our micro-mechanical elasticity model for micellar filaments [Asgari, Eur. Phys. J. E 2015, 38(9)], the elastic bending energy of hemispherical end caps is found. The continuum description of the elastic bending energy of a cylindrical micellar filament is also derived using constrained Cosserat rod theory.

split hopkinson pressure bar (SHPB)

I am modelling a SHPB assembly together with the specimen, I seem to still be having problems with my results.In the definition of step time I encountered a problem, please advise me. When I plot my Stress/Time curve to get a pulse the graphs all seem to be wrong.My curve instead of a neat pulse is a series of undulating peaks and valleys, can you please send the same inp file simualtion shpb to me also at

I know this was done a long time ago but it would be a great help if you can still find it for me.

Best regards

(Due 31st October) Call for Nominations for the Eshelby Mechanics Award for Young Faculty

It is my pleasure to solicit nominations for the "Eshelby Mechanics Award for Young Faculty". This award, launched in 2012, is given annually to rapidly emerging junior faculty who exemplify the creative use and development of mechanics. The intent of the award is to promote the field of mechanics, especially among young researchers. While interdisciplinary work that bridges mechanics with physics, chemistry, biology and other disciplines is encouraged, the ideal awardee will demonstrate clear inspiration from mechanics in his/her research.

A new hybrid numerical scheme for modeling elastodynamics in unbounded media with near-source heterogeneities

The Finite Difference (FD) and the Spectral Boundary Integral (SBI) methods have been used extensively to model spontaneously propagating shear cracks in a variety of engineering and geophysical applications. In this paper, we propose a new modeling approach, in which these two methods are combined through consistent exchange of boundary tractions and displacements. Benefiting from the flexibility of FD and the efficiency of spectral boundary integral methods, the proposed hybrid scheme will solve a wide range of problems in a computationally efficient way.
