This webinar will highlight effective 3D blade design approaches to design high pressure ratio centrifugal compressors and ease of shock control to achieve high stage performance.
Short Abstract:
Hello everyone,
Optomechanics of Soft Materials
Ruobing Bai and Zhigang Suo
The Fluid Dynamics and Solid Mechanics Group (T-3) at Los Alamos National Laboratory is currently seeking outstanding candidates for a post-doctoral research position in the areas of solid mechanics, constitutive modeling, computational methods, and multi-scale modeling and simulation techniques. The prospective candidate is expected to take part in theory and computational method development for the effective representation of plasticity, damage and failure in solid materials.
We know "Many experiments have shown that ductile materials can be hydrostatically stressed to levels beyond their ultimate strength in compression without failure. This is because the hydrostatic state of stress reduces the volume of the specimen without changing its shape. My confusion is that in what stress value the failure is occure under hydrostatic pressure?
Naturally, I do not expect that a metal can bear infinite hydrostatic pressure values!

We are looking for three postdoctoral researchers to work at Nanyang Technological University, Singapore.
1. Two researchers are to work on water remediation and desalination using computational methods at the atomistic level.
2. One researcher is to work on fracture behavior of weldments using computational methods at the microstructural leve.

To improve further computational tools for fracture, we need a
talented phd. We are developping transition models from damage
to fracture for several type of materials (quasi-brittle and ductile).
The position will be open until filled. Please send me your CV
if you are interested.
The theoretical framework is the Thick Level Set model for damage (TLS)
and the numerical implementation uses level sets and the extended
finite element method (X-FEM).
The research team currently gathers 9 persons.
