Postdoc Fellow Position about Energy Design at Virginia Tech
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. Prototypes of 5kW - 30KW will be designed, tested, and demonstrated in both labs and in oceans.

Reinforced Concrete Strength
The composite strength of Reinforced Concrete which is a mixture of two main materials can be calculated by the formula given by Tsai : X=(vf+vm*Em/Ef)*Xf where vf is the fiber (steel) fraction and vm is the concrete (cement+sands+gravels) fraction. Xf is the yield strength of Steel and Xm is the compressive strength of the Concrete matrix. For the application case: vf=0.01911, vm=0.98089, Xf=270 MPa, Xm=40 MPa, Ef=207.000 GPa, Em=30.798 GPa we obtain X=44.563 MPa.
Shape Bifurcation of a Spherical Dielectric Elastomer Balloon under the Actions of Internal Pressure and Electric Voltage
Under the actions of internal pressure and electric voltage, a spherical dielectric elastomer balloon usually keeps a sphere during its deformation, which has also been assumed in many previous studies. In this article, using linear perturbation analysis, we demonstrate that a spherical dielectric elastomer balloon may bifurcate to a nonspherical shape under certain electromechanical loading conditions.
Superpositon Principle? how to understand
I have a question about the superpositon principle in Elasticity Mechanichs. Does there exist such a state which can composited to one plane stress state and plane deformation?
Two-year Postdoctoral position on stochastic multi-scale methods
A reliable numerical model is crucial for the design and analysis of modern dynamic engineering systems such as automobiles, helicopters and aircrafts. Uncertainties should be taken into account for credible predictions of quantities of engineering interest of such systems (such as internal stresses, vibration levels). Uncertainties in complex systems include (a) parametric uncertainty (e.g.
RILEM Multi-scale Modelling Course for Concrete (MMC2)
The RILEM Multi-scale Modelling Course for Concrete (MMC2) provides the opportunity for participants to become familiar with modelling cementitious materials at four different levels of detail. Different ways of schematization and numerical approaches are considered to simulate the chemical, physical and mechanical behaviour of cementitious materials.
