PhD Position in Atomistic Simulations / Computational Fracture Mechanics
The Institute for General Materials Properties of the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) is seeking outstanding candidates for the project “microKIc – Microscopic Origins of Fracture Toughness”, which is funded by an ERC Consolidator Grant.
Abaqus/Python - commands to find nearest node to a given point
Hi,
I need to write a python comman code to find a node (in a given set), nearest to a given point.
The code now looks as follows:
import sys
sys.path.insert(10,
r'c:/SIMULIA/Abaqus/6.13-3/code/python/lib/abaqus_plugins/findNearestNode')
import nearestNodeModule
nearestNodeModule.hideTextAndArrow()
a = mdb.models['FibreModel'].rootAssembly
n1 = a.instances['Fibre0-1'].nodes
pickedSelectedNodes = n1[0:599]
g=nearestNodeModule.findNearestNode(xcoord=101, ycoord=106, zcoord=58, name='', selectedNodes=pickedSelectedNodes, instanceName="'Fibre2-1'")
help to wright umat for multi yield surfaces j2 plasticity model
Hi every one. Im working on multi yield surfaces j2 plasitisity and if its possible i want add cappability to predict time dependant hehaivior of geomaterials. to start i must wright an umat code for multi yield surfaces j2 model. please help me how can i find it or give me any information about it. thanks for every one.
Time to Register for 2017 American Society for Composites Annual Conference at Purdue
Dear Colleagues, if you are interested in the state-of-the-art R&D in composite materials, you might want to attend the American Society for Composites Anuual Meeting at Purdue (10/22-25, 2017). The registeration is open at https://cdmhub.org/groups/asc2017/registration
Identification of higher-order continua equivalent to a Cauchy elastic composite
Dear Mechanician,
A novel method for the identification of higher-order continua equivalent to a Cauchy composite has been published, as a result of the collaboration between the following two ERC projects:
http://erc-instabilities.unitn.it
http://musam.imtlucca.it/CA2PVM.html
Full paper:

Abstract:
Posdoc in Smart Manufacturing of Composite Materials
The candidate will work in a project related with smart manufacturing of composite materials by injection/infusion techniques. The project will consist in a joint collaboration between Data Mining Research Group from Universidad Politécnica de Madrid (UPM) and IMDEA Materials Institute.The research activities will be focussed on the application of simulation techniques (computational fluid mechanics) to the optimization of manufacturing process of composite materials by liquid moulding, including the creation of a physical demonstrator.
Two recent papers - one related to head impact and the other on orthotropic Kirchhoff plates
These two papers have recently been published in Int. J. Mech. Sci. and Acta Mech.:
1) Analytical Models for the Impact of a Solid Sphere on a Fluid-Filled Spherical Shell Incorporating the Stress Wave Propagation Effect and their Applications to Blunt Head Impacts

2) A non-classical model for an orthotropic Kirchhoff plate embedded in a viscoelastic medium
Unusually low and density-insensitive thermal conductivity of three-dimensional gyroid graphene
http://dx.doi.org/10.1039/C7NR04455K Graphene has excellent mechanical, thermal and electrical properties. However, there are limitations in utilizing monolayers of graphene for mechanical engineering applications due to its atomic thickness and lack of bending rigidity. Synthesizing graphene aerogels or foams is one approach to utilize graphene in three-dimensional bulk forms. Recently, graphene with a gyroidal geometry has been proposed.
