Uniaxial compression of heterogeneous/cellular material (bone)
Dear colleagues,
I kindly ask for advice on the following problem:
I simulate the uniaxial compression of a heterogeneous cylinder representing bone. Thus, it is not the visible solid exterior rim of the bone, but represents a porous structure within the bone, so-called trabecular bone, see the figure underneath.
The simulation is done in ABAQUS. The sample contains 164175 elements of type C3D4. The heterogeneous, porous structure makes it impossible to use axisymmmetric elements. The constitutive behavior is ELASTIC.
FINITE ELEMENT WEAR SIMULATION
hi all,
i am very new to abaqus and i want to simualte sliding wear between a pin and a disc. i found from the literature that by using user subroutines we can calculate the wear. i am not getting how to use a user subroutine , can any one expain how to use user subroutines in the CAE. is there any simple example problems in understanding this user subroutine functions. thanks in advance.
Post-doc, JRC-Petten: Microstructural characterisation of materials and mechanical property correlation
The Joint Research Centre of the European Commission,Insitute for Energy (IET), in Petten Nehterlands, is looking for a motivated scientist or engineer at post-doctoral level to work on characterization of primarily metallic materials for nuclear reactors using a combination of techniques such as scanning and transmission electron microscopy (SEM and TEM), energy-dispersive X-ray spectroscopy (EDX), Xray diffraction (XRD), and 3D X-ray tomography.

Postdoc positions at MIT's Department of Materials Science and Engineering
Postdoctoral positions are currently available at MIT's Department of Materials Science and Engineering for individuals with a strong background in materials simulations. Experience in atomistic methods (both classical potential or first principles) or mesoscale methods (e.g. phase field or dislocation dynamics) is preferred. Projects will focus on several different aspects of grain boundary and heterophase interface properties in metals. There are no citizenship requirements associated with these
EC FUNDED WORKSHOP ON PHYSICS BASED MODELING OF MATERIALS, Ankara, October 22-23
The objective of the workshop, co-organized by Joint Research Centre of the European Commission and Middle East Technical University, is to discuss the present status of physics based constitutive modelling of metallic materials and associated experimental methods.
The Workshop is funded by the European Commission's Integration and Enlargment Programme. There is no cost for attending the Workshop. A limited number of scholarships is available for participants from the target countries (see attached flyer).
