Reconstruction of the 3D representative volume element from the generalized two-point correlation function

Submitted by ystarase on

This paper presents the first application of three-dimensional (3D) cross-correlation 
microstructure reconstruction implemented for a representative volume element (RVE) to 
facilitate the microstructure engineering of materials. This has been accomplished by 
developing a new methodology for reconstructing 3D microstructure using experimental two-
dimensional electron backscatter diffraction data. 

how can i model a BRB Brace in abaqus

Submitted by mohammadi11 on

hi every body


I model a brb(Buckling restrained brace) in Abaqus but my question is How to put concrete in a brb or How do I define the concrete inside the brb that work together? i use tie constraint But there isn't any stress for concrete! 
i use static,General for analysis! is it correct? 

Summer School - HPC for Engineering Simulation

Submitted by Lee Margetts on

The STFC Hartree Centre (in Warrington, UK - located between Manchester & Liverpool) is running 4 high performance computing summer schools from June to July 2016. They are primarily aimed at PhD students and postdoctoral researchers, but are also open to academics and industry at no extra cost. The tuition fees are subsidised by STFC and each week only costs £150. There is a 1 week school on each of the following topics:

Post-doctoral position in Computational Materials Mechanics at NUS, Singapore

Submitted by Shailendra on

We have an opening for a post-doctoral fellow position in multiscale computational mechanics of polymers. The project focuses on modeling and simulation of the thermo-mechanical behavior of polymers with covalent adaptable networks (CANs), e.g. vitrimers. The objective is to formulate a hierarchical modeling and simulation approach, which closely mimics key steps in the recycling and reshaping processes of CAN polymers by embedding the physics at two length-scales – (i) discrete-continuum (meso-scale) and (ii) homogenized continuum (macro-scale).

Hi friend,

I have three volumes. I did modal analysis in apdl ansys on them But I have errors:

Element type 1 is unknown, which cannot be used with the vmesh command, meshing of volum 1 abborted.

my apdl code is:

Hi everybody;

I have three volumes in ansys, I did modal analysis on them in apdl ansys but I have an error from VMESH  command for external volum(volum 1) please help me, how can correct it?

my model, errors and my apdl code in ansys is attached:
