Two open PhD positions in multi-physics process and performance modeling of alloys at the University of Tennessee

We have two open PhD position starting in the Fall semester 2020 at the Computational Laboratory for the Mechanics of Interfaces at the University of Tennessee - Knoxville (http://clmi.utk.edu). First research topic centers upon the modeling of texture evolution during processing (e.g. cogging and rolling) of titanium alloys using crystal plasticity and Fast Fourier Transform methods to couple the mesoscale and specimen scale.

Postdoc position available at Columbia University in the City of New York

We have one or more postdoc positions available, to be filled immediately, in my research group. We are looking for postdocs in the broad area of computational mechanics.  Candidates should have expertise in modeling dynamic responses of path-dependent materials. Our project is specifically focused on the development and validation of multiscale models for energetic/porous/polycrystalline materials across length scales. More details will be provided to interested candidates.

Critical porosity in the fatigue of additively manufactured IN718 via crystal plasticity modeling

https://doi.org/10.1016/j.matdes.2018.04.022

Highlights

1. Critical porosity is estimated in additively manufactured IN718 via crystal plasticity.

2. Porosity is characterized using high resolution tomography.

3. Non-local damage indicator parameters identify the location of fatigue crack initiation.

Open PhD position in multi-scale process modeling of titanium alloys at the University of Tennessee

We have an open PhD position starting in the Fall semester 2019 at the Computational Laboratory for the Mechanics of Interfaces at the University of Tennessee - Knoxville (http://clmi.utk.edu). The research topic centers upon the modeling of texture evolution during processing conditions of titanium alloys using dislocation density based crystal plasticity. Efficient computational algorithms will be pursued to couple the specimen/part scale and the mesoscale.

Effect of Loading on Slipping of Crystal Planes

We know when a metal is subjected to proper loading, there exists plastic strain. A great part of plastic strain is developed from the slipping of the crystal planes of that metal in microstructure level. Now, when the load is uniaxial, it is simple to calculate the amount of shear strain acts on that plane. But, when the load is not uniaxial, the life is harder. It is very hard to calculate which slip plane feels how much shear strain.

Postdoc Position on computational mechanics of polycrystaline rocks

Dear colleagues, 

A postdoc position is immediately available in my research group. Experience on derivation, implementation, validation and verification of crystal plasticity model at finite strain is required. Knowledge on meshless method and/or phase field modeling is a plus but not required.

Simulation of crack growth in Ni-based single crystals

In a cooperative research between PoliMi and UIUC we have analyzed the crack growth in Ni-based single crystals:

http://www.sciencedirect.com/science/article/pii/S0142112316000840

 Crack growth experiments analyzed with DIC had shown relatively low closure levels respect to polycrystals. Crystal plasticity simulations with WARP3D have been able to simulate closure levels consistent with the experimental ones.

Polycrystal plasticity in Abaqus/Explicit

Choose a channel featured in the header of iMechanica: 

Hello everyone!

My goal is to model large plastic deformations of polycrystalline metals using crystal plasticity and ALE adaptive meshing. In order to do that I want to use VUMAT subroutine in Abaqus/Explicit, since as far as I understand Abaqus/Standard is not good for large deformations and it doesn't support ALE adaptive meshing for that purpose.

Phase field modeling of damage and fracture in polycrystalline materials, support from the Chinese Scholarship Council

The ability of scientists and engineers to exploit, design and process new materials with improved properties has often been fundamental for the technological advances of societies. In fact, advances in many key domains like aerospace, automotive industry, energy, nanotechnology, rely on our ability to engineer new materials and to exploit their properties.
