Ryan C. Hurley of the Johns Hopkins University will be the next Editor of the iMechanica Journal Club. The Journal Club was initiated in January 2007, soon after the launch of iMechanica. It has quickly grown into a flagship feature of iMechanica, epitomizing the vibrant topics and dynamic researchers at the frontier of mechanics.

We are looking for self-motivated and enthusiastic students with a degree in mechanical or materials engineering. Students with following backgrounds are strongly recommended to apply:

The fracture of concrete and other semi-brittle materials offers some simplifications that simplify the analytical analysis. The simple check that reveals if something broken requires an elastic or an elastic-plastic fracture mechanical analysis by just trying to fit the pieces together sometimes fails. The suggestion is that if they do not fit together, we have an elastic-plastic fracture and if they do we have an elastic fracture. We may jump to the false conclusion that linear elastic fracture mechanics can be applied.

The Gu Research Group at UC Berkeley has postdoc positions available in the areas of computational fluid dynamics, aerodynamics, and aeroelasticity. Interested candidates should contact Prof. Grace Gu at ggu@berkeley.edu and attach your CV. 

Postdoctoral positions are immediately available in the Department of School of Traffic and Transportation Engineering (First Class Academic Discipline) at Central South University in Dr. Li research group. Dr. Li’s research focuses on the theoretical, experimental, and computational studies of the mechanics of advanced materials and structures. The candidates are required to have expertise in one of the following areas:

Postdoc positions are available in Dr Min Luo’s group (https://person.zju.edu.cn/en/minluo) at the Ocean College of Zhejiang University, China (ranked #45 in QS Global World Rankings 2022).

The transition between necking-mediated tensile failure of glasses, at elevated temperatures

and/or low strain-rates, and shear-banding-mediated tensile failure, at low temperatures and/or

high strain-rates, is investigated using tensile experiments on metallic glasses and atomistic simula-

tions. We experimentally and simulationally show that this transition occurs through a sequence of

macroscopic failure patterns, parametrized by the ultimate tensile strength. Quantitatively analyz-

Understanding the fracture toughness of glasses is of prime importance for

science and technology. We study it here using extensive atomistic simulations in

which the interaction potential, glass transition cooling rate, and loading geometry

are systematically varied, mimicking a broad range of experimentally accessible

properties. Glasses’ non-equilibrium mechanical disorder is quantified through

Ag, the dimensionless prefactor of the universal spectrum of non-phononic

In this project, the research fellow is expected to work on the K&C concrete model in LS-DYNA. Focusing on normal strength concretes of ~45 to 60 MPa compressive strengths, the research fellow has to calibrate the material parameters against experimental data, and to establish all modelling inputs for simulating the response of concrete structures against very high impact loading conditions. The numerical predictions will be benchmarked against experimental data.

We developed an inverse design method for constructing 3D reconfigurable architected structures — we synthesized modular origami structures whose unit cells can be volumetrically mapped into a prescribed 3D curvilinear shape followed by volumetric shrinkage for constructing modules. After modification of tubular geometry, we searched modular origamis’ geometry and topology for target mobility using a topological reconstruction of modules.

Traditionally dynamic analysis is done using Newton’s universal laws of the equation of motion. According to the laws of Newtonian mechanics, the x, y, z, space-time coordinate system does not include a term for energy loss, an empirical damping term “C” is used in the dynamic equilibrium equation. Energy loss in any system is governed by the laws of thermodynamics. Unified Mechanics Theory (UMT) unifies the universal laws of motion of Newton and the laws of thermodynamics at ab-initio level.

 PhD Students - 2023

Our group in the Department of Mechanical and Industrial Engineering at New Jersey Institute of Technology (NJIT) is working on a range of problems, involving mechanics and physics of 2D materials, soft materials and biological systems. We employ methods of continuum mechanics, mathematics, statistical physics and atomistic simulations to explore the mechanics of 2D materials, electromechanical coupling in soft materials, as well as physical mechanisms underlying the interface of nanomaterials and biology.

Our ice mechanics group at Aalto University (Finland) is looking for a PhD-student to work on offshore wind in cold sea areas. We will use discrete element method to study how drifting sea ice affects an offshore wind farm and how the wind farm affects the sea ice surrounding it.
