Nanobrücken 2016: A Nanomechanical Testing Workshop & Hysitron User Meeting

Submitted by Douglas Stauffer on Fri, 01/15/2016 - 14:47

Nanobrücken 2016: A Nanomechanical Testing Workshop & Hysitron User Meeting will take place March 2nd - 4th, 2016 at the INM - Leibniz Institute for New Materials in Saarbrücken, Germany. This will be the 6th edition of the now-annual Nanobrücken workshop series.

As in the past, the workshop is open to all aspects of nanomechanical and nanotribological testing, including biomechanical, in-situ experimentation and theory/simulation.

Merge mesh in Abaqus

Hi I tried to mesh these two plates with two cases having different geometries. I am trying to achieve something similar in complex geometry in abaqus. But I think the problem is with shapes or if it is something else, please help me with this. I tried in solid elements too it did not work either. I have attached image where you can see two cases

Please see the attached file for detailed view

finding contact time from maximum displacement for hertzian contact

Submitted by rctron on Thu, 01/14/2016 - 16:50

While going through the derivation of contact time for a hertzian contact as given in problem 3 at the following link http://s17.postimg.org/t1kq6mlxr/Capture.png , I am not able to understand how the integral form for contact time has come into picture. Can anyone explain the in-between steps to get the same? I understand that this is a very trivial problem but it will be a great help to understand the steps. Thanks.

Influence of interface and strain hardening cementitious composite (SHCC) properties on the performance of concrete repairs

Submitted by shavijabranko on Thu, 01/14/2016 - 09:01

Mladena Lukovic of Delft University of Technology (Netherlands) has successfully defended her thesis dealing with mechanics and physics of concrete repair systems on 6th of January. Her thesis can be downloaded at http://repository.tudelft.nl/view/ir/uuid:28b07d9b-c704-47fa-9ba3-cd9fd… , and is of interest to everyone dealing with discrete modelling and micromechanical testing of cementitious and other quasi-brittle materials.

graphite; multi-scale modelling; quasi-brittle fracture

Dear all,

Our group has just published a paper on experimentally-informed multi-scalle modelling of nuclear graphite in the journal of Engineering Fracture Mechanics. It can be of interest to anyone working on quasi-brittle fracture and materials such as graphite, concrete, rock, shale, or similar. It can be downloaded at:http://www.sciencedirect.com/science/article/pii/S0013794415007080

job

A postdoctoral associate position is available at Department of Petorleum Engineering, Texas A&M University in the area of resistivity characterization of geomaterials. Experimental characterization at nano-scale will be combined with modeling techniques to get insight into electrical properties of geomaterials at fundamental length scales. Expected qualifications:A Ph.D. in materials science, civil engineering, geophysics or a related field is required.
