The Rubber Division, ACS is now accepting online
abstract submissions for the 182nd Technical Meeting being held during the
Rubber Expo at the Duke Energy Center, October 9-11, 2012, in Cincinnati, OH,
USA.  Papers will be judged and awards presented
for Best Paper and Best Paper - Honorable Mention.

I am co-organizing a mini-symposium on « Computational damage mechanics of composite materials »  in the World Congress on Computational Mechanics (WCCM 2012) with Dr. Gilles Lubineau at King Abdullah University of Science and Technology (KAUST) and Dr. Glaucio H. Paulino at the University of Illinois at Urbana-Champaign.

The mini-symposium welcomes contributions highlighting the critical role of virtual design and simulation in the development of advanced composite structures. Discussions held will cover a variety of topics, however the focus will be upon application-oriented problems through which simulation and modeling can provide real added-value with respect to pure experimental design approaches.

September 17-19, 2012, Beijing, P.R. China

Abstract 

Elastomers and gels can be formed by interpenetrating two polymer networks on a molecular scale. This paper develops a theory to characterize the large deformation and damage of interpenetrating polymer networks. The theory integrates an interpenetrating network model with the network alteration theory. The interpenetration of one network stretches polymer chains in the other network and reduces its chain density, significantly affecting the initial modulus, stiffening and damage properties of the resultant elastomers and gels.

The Department of Materials Science and Engineering in the College of Engineering at the University of North Texas (UNT) seeks highly qualified applicants for a postdoctoral researcher position in computational materials modeling. The successful candidate will work on multiscale modeling of defects and microstructures (e.g., dislocations, grain boundaries, etc), and damage and failure of materials to design and evaluate advanced superalloys for aerospace applications, as part of the federally-funded research program in the Institute for Science and Engineering Simulation (ISES).

Qualifications:
1.    A PhD in solid mechanics, materials science, or mechanical engineering, or in a related area is required.

Elastomers are outstanding in their ability to repeatedly endure large deformations, and they are often applied where fatigue performance is a critical consideration. Because the macromolecular structure of elastomers gives rise to a number of unique behaviors, appropriately specialized methods are needed to characterize, analyze, and design for durability. This 2-day course provides the know-how for engineering durable elastomeric components and systems. The course is taught at Axel Products, and includes live demos of typical behavior.

Salam and Hi!

Can anyone share here, your understanding on POST BUCKLING and PROGRESSIVE DAMAGE ANALYSIS.

Hi all,

     Here I encoutered a error in ABAQUS when I include ALE with VUMAT. When ALE was not included with VUMAT, my job can work well while with the combination of VUMAT and ALE, the job cann't work any more due to a "Signal 8" error. And if I use a built-in material model and at the same time ALE, a job can work. Furthermore, element failure is considered in all of the cases.

    Anyone can give some suggetion? Thanks in advance!

Xinke

Hi all,

     Can anyone give a description on the diffrence of ALE in ABAQUS and LSDYNA? And also the difference between r-adaptivity and ALE in ABAQUS. It seems ALE in ABAQUS means the same with r-adaptivity in LSDYNA while “ALE” means diffrently in the two codes.

      Thanks a lot!

Dear iMechanicians,

It seems that nobody here is active in fatigue life prediction focused on the initiation period. I believe it should be here and do not understand why the fracture mechanics has its place here but the initiation of cracks has been forgotten. Although cracks are very interesting there is a lot industrial sectors, where they are not wanted. Is not the reason of the current situation that the available computational tools that are free are mostly related to crack growth?

Regards,

Jan Papuga

Currently, i am now attempting to establish a plasticity/damage coupling model using continuum damage mechanics for complex metal structures such as steel pressure vessel, which can be implemented using finite element analysis. The model can predict the progressive failure and damage evolution as well as the crack initiation and propogation due to large plastic deformation of metal structures. Who can give me some suggestion or idea?

A one year (renewable) post-doc position is avalaible at the Ecole Centrale of Nantes, France.

The research deals with the simulation of complex cracking patterns in composites using

 the eXtended Finite Element method (X-FEM).

To apply : a CV + name of at least two references.

The Australian Mineral Science Research Institute (AMSRI) is a consortium of Australia's best scientists working in minerals industry-related fields. Research activities span the breadth of minerals processing, with major themes of the research being energy efficiency, frugal water use and efficient management of waste. The Mathematics program of AMSRI performs modelling and analysis research across multiple minerals processing areas, including comminution, flotation and waste treatment.

A technique for setting up generalized continuum theories based on a balance law and nonlocal thermodynamics is suggested. The methodology does not require the introduction of gradients of the internal variable in the free energy. Elements of a generalized damage model with porosity as the internal variable are developed as an example.
