Post-Doctoral Fellowship: Looking for energetic researchers with strong background in constitutive modeling or multiscale material simulations. Specialty on fatigue and fracture of metals, polymer or short fiber composites is a plus.  The primary research will be focused on physics-based damage, fracture, and fatigue modeling and simulations at various scales.  If interested, please contact Dr. Yibin Xue via email or visit her website.

I post some (hand-written) notes on compatibility conditions for both small and finite strains that I have used for helping me in lecturing. These may be useful for our student friends on imechanica. I also post a paper on compatibility conditions for the Left Cauchy-Green field in three dimensions as well as the paper by Janet Blume on the same subject.

recommend more references about this topic: S. van der Zwaag Editor, Self Healing Materials-An Alternative Approach to 20 Centuries of Materials Science. Springer, 2007.  about half of this book talk self healing polymers.

For the 2009 solicitation, we will consider proposals that aim to investigate emerging frontiers in the following two specific research areas:

1. BioSensing & BioActuation: Interface of Living and Engineered Systems (BSBA)
2. Hydrocarbons from Biomass (HyBi)

Due dates

Highly motivated PhD or MS/PhD candidates are sought for
research in computational mechanics and inverse problems in the Department of
Civil and Environmental Engineering at the University of Pittsburgh.

We have six strain compatibility equations, which are obtained from strain-displacement relations by making an assumptions 'small strains'. Strain compatibility equations ensure a single valued and continuous displacemnet filed. These equations are used in stress based approach.

Now my queries are as following.

[1] Do we have strain compatibility equations for non-linear strain-displacement relations?

[2] Do we follow stress based approach in non-linear solid mechanics.

I am a third yr undergraduate student of Aerospace Engineering department, IIT Kharagpur. I have a very simple question in strucutral mechanics. Is there any analytical solution available for deflection of plate under distributed load? The governing equation is well known and has been attached as an image file. Only classical plate theory can be considered. The boundary conditions can be taken as classical boundary conditions. So that can be any combination of a) hinged b) clamped and c) free boundary conditions.
