Temperature Dependent CTE (coefficient of thermal expansion)

Hello People,

Would anyone please tell me or provide any documentation for how to find Temperature Dependent CTE (coefficient of thermal expansion) or modulus of elasticity? I have water which is encapsulated in box made of steel and which goes under freezing process and water expands. 

So i need any mathematic relations for water and metal as well to fine CTE.

Thanking you,

Rohan

2 Post Doctoral researcher positions in Computational Mechanics of Materials

Two post doctoral positions are available at the University of Limerick, Ireland. The object of the research, which is funded by Science Foundation Ireland (SFI), is to obtain an understanding of the mechanical behaviour of ferritic and martensitic steels at the micron and sub-micron scale and to link this behaviour to component behaviour. The work will involve computational and experimental studies of material behaviour using a range of numerical and experimental techniques.

Dynamic instabilities of frictional sliding at a bimaterial interface

Understanding the dynamic stability of bodies in frictional contact steadily sliding one over the other is of basic interest in various disciplines such as physics, solid mechanics, materials science and geophysics. Here we report on a two-dimensional linear stability analysis of a deformable solid of a finite height H, steadily sliding on top of a rigid solid within a generic rate-and-state friction type constitutive framework, fully accounting for elastodynamic effects.

Positions available in the mechanics of polymers

Two positions at the PhD level are available in solid mechanics in my group in the Mechanical and Industrial Engineering Department at the New Jersey Institute of Technology.  I'm looking for motivated students in the area of solid mechanics and materials, with specific application to the multiphysics behavior of polymeric materials.  A few key areas are polymeric gels, thermo-mechanics of polymers, shape-memory polymers, chemical reactions occurring in a deforming polymer, and so on.  Research topics are broad and cover the full range of theoretical, numerical, and experimental aspects.

Large-eddy simulation with near-wall modeling using weakly enforced no-slip boundary conditions

In the present paper, weakly enforced no-slip wall boundary conditions are revisited in the context of Large-Eddy Simulations (LES) with near-wall modeling. A new formulation is proposed in the framework of weakly enforced no-slip conditions that is better aligned with traditional near-wall modeling approaches than its predecessors.

Syringe-injectable electronics

Seamless and minimally invasive three-dimensional interpenetration of electronics within artificial or natural structures could allow for continuous monitoring and manipulation of their properties. Flexible electronics provide a means for conforming electronics to non-planar surfaces, yet targeted delivery of flexible electronics to internal regions remains difficult.

Design of planar isotropic negative Poisson’s ratio structures

Most of the auxetic materials that have been characterized experimentally or studied analytically are anisotropic and this limits their possible applications, as they need to be carefully oriented during operation. Here, through a combined numerical and experimental approach, we demonstrate that 2D auxetic materials with isotropic response can be easily realized by perforating a sheet with elongated cuts arranged to form a periodic pattern with either six-fold or three-fold symmetry.

Opening for new Ph.D. students in the Computational Mechanics group, The University of Iowa.

The Computational Mechanics group at The University of Iowa, led by Professor S. Rahman, is looking for new Ph.D. students, who are capable of and interested in performing high-quality research on engineering design. The research, supported by National Science Foundation and others, entails building a solid mathematical foundation, devising efficient numerical algorithms, and developing practical computational tools for stochastic design optimization. A substantial background in solid mechanics and structural optimization is a must; exposures to stochastics and probabilistic methods are highly desirable.

If you are interested in pursuing a Ph.D. degree at Iowa, please contact and send a resume to: Professor Sharif Rahman at sharif-rahman@uiowa.edu. Please note that we are interested in students who already have M.S. degrees in engineering or mathematics. The desired start date is Spring 2016 or sooner.

PhD or Postdoc position in Materials Mechanics/Numerics/Statistical Physics

Development of advanced materials for high-end applications is driven by the increasing understanding of the dynamics and properties of defect microstructures, leading to the ability to synthesize and control materials microstructures to meet specific application demands. Dislocation motion is the fundamental physical mechanism of the plastic deformation process in crystalline materials.

Multistable Architected Materials for Trapping Elastic Strain Energy

3D printing and numerical analysis are combined to design a new class of architected materials that contain bistable beam elements and exhibit controlled trapping of elastic energy. The proposed energy-absorbing structures are reusable. Moreover, the mechanism of energy absorption stems solely from the structural geometry of the printed beam elements, and is therefore both materials- and loading-rate independent.
