Three fully funded PhD positions are available in Dr. Lei Zuo's group in the department of mechanical engineering at Virginia Tech starting from Fall, 2016. One opening is about design and control of wave energy converter, one is on vibration energy harvesting fro oil drilling system and another one is about energy harvesting from backpack while human walking or running.
A postdoc position is available immediately for an externally funded project on ocean wave energy in the department of Mechanical Engineering, Virginia Tech. The objective is to develop and test a novel mechanical solution for converting ocean wave energy into electricity.

A simplified one dimensional rate dependent model for the evolution of plastic distortion is obtained from a three dimensional mechanically rigorous model of mesoscale field dislocation mechanics. Computational solutions of variants of this minimal model are investigated to explore the ingredients necessary for the development of microstructure. In contrast to prevalent notions, it is shown that microstructure can be obtained even in the absence of non-monotone equations of state. In this model, incorporation of wave propagative dislocation transport is vital for the modeling of spatial patterning. One variant gives an impression of producing stochastic behavior, despite being a completely deterministic model. The computations focus primarily on demanding macroscopic limit situations, where a convergence study reveals that the model-variant including non-monotone equations of state cannot serve as effective equations in the macroscopic limit; the variant without non-monotone ingredients, in all likelihood, can.

Special Issue on 3D Assembly by Cutting, Bending and Folding in Extreme Mechanics Letters
When patterned with different materials, gradients or cut-outs, thin structures such as sheets and rods can bend or fold either spontaneously or by actuation in response to a force or stimulus to form a pre-designed three dimensional structure. This special issue addresses the design and mechanics of these structures with a special emphasis on programmability and non-linearity.

Multiple Ph.D. fellowships are available at Clemson University in the broad area of model validation and data analytics through a recent Graduate Assistance in Areas of National Need (GAANN) grant. Through this grant, faculties from Civil Engineering, Environmental Engineering and Earth Science, Mathematical Science, and Computer Science team up to work on the national need for model validation analytics in civil and environmental engineering problems.
Dear Colleagues,
15th European Mechanics of Materials Conference (EMMC15) will be held in Brussel, Belgium, during 7 – 9 Sentember, 2016. As part of this meeting, we are organizing a session (S7) to bring together experts in modelling, simulation, manufacturing and experimental investigation in the field of functional and architectured materials to present and discuss recent advances. Topics of particular interest include (but not limited to)
Abstract: In this paper, we provide a retrospective examination of the developments and applications of the extended finite element method (X-FEM) in computational fracture mechanics. Our main attention is placed on the modeling of cracks (strong discontinuities) for quasistatic crack growth simulations in isotropic linear elastic continua.
