Abstracts for the 2011 APS Topical Conference on Shock Compression of Condensed Matter are now being accepted. This biennial meeting is the premier conference for shock compression, behavior of materials at high pressures and high strain rates, and related areas. We hope you will be able to join us for an outstanding Conference in Chicago, Illinois, June 26 - July 1, 2011.
A Ph.D. candidate position is available in Computational Solid Mechanics and Materials at Florida Institute of Technology. Ideally the applicant holds a M.S. degree. Those outstanding graduates with B.S. degree would also be considered. It is expected that the candidate has a background in computational stress and fracture mechanics analyses and/or computational materials science. The project will be on Materials and Mechanics Issues in Energy Storage, specifically, in lithium ion batteries and solid state hydrogen storage. The position starts in Spring, 2011.
I am going to simulate the well-known welding process i.e.
ultrasonic welding process for thermoplastics using ANSYS. I am using ABS first
of all. My sample dimensions are 30*40*1 and one of these two parts will be
having an energy director of triangular shape at its centre with an overall
thickness of 1.5 being equally distributed from the centre.
The parts to be welded are placed on the anvil and after
proper fixturing, ultrasonic vibrations are applied at the upper part under a
pressure of 2.0775E6.
My last two posts on this series
Part- 1 (node/9016) and
Part- 2 (node/9073)
were mainly focussed on the tension–torsion (σ11–√3σ12) stress space. This paper will be the final post on this series and will focus mainly on the behavior of both of these alloys under tension–tension (σ11–σ22)space and conclude this ongoing research.
Abstract.
At the Laboratory for Computational Mechanics and Materials Science at Monash University, we have two openings for Ph.D candidate positions in the general area of computational mechanics and materials physics.
The material systems that we are interested in—for example, graphene, semiconductor nanowires and quantum dots—are relevant for nanotechnology and energy applications. The current research topics are multidisciplinary in nature, and offer an excellent opportunity for close interactions with experimentalists and with international collaborators.
Hello to all,
I`m carring out a simulation with abaqus of an underground storage tank. I modelled the tank using shell elements (conventional) and for the soil I used solid element. I want the stress on the top of the tank caused by the efect of the soil that is on the top.
The applied load is Gravity in the y-direction (-10 m/s2) to the whole model and I`m using abaqus/standard. I defined the contact between the tank and the soil.
The problem is that the job end saying "too many attemps for this increment". I used different increments but all of them with the same result.
What can I do or what am I missing ?
Thanks to all!
Ezequiel
We are no longer accepting applications for this position. Qualified applicants will be contacted in the near future.
Thank you for your interest,

Multiple Ph.D. positions are available in the area of Computational Solid Mechanics in the Dept. of Civil & Environmental Engineering at the University of South Carolina. These positions will begin in August 2011, and fully cover university tuition and stipend.
Hello ! I'm a beginner in Abaqus and for that I've tried to follow this tutorialhttp://fliiby.com/file/831535/i3rkmyhurs.html .
I was all ok until I tried to make the mesh (chapter 3.7.2 in tutorial). It said that they are parts of the assemby that are too complex to be meshed with those mesh settings.
The problematic zone is this:
