Ph.D. candidate position at Florida Institute of Technology

Submitted by Bo Yang on

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.

[Dynamics] Ultrasonic Welding of thermoplastics

Submitted by farchee500 on

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.

Evoution of Yield surfaces: Past and Future Trend - Part 3

Submitted by Amit Pandey on

 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 (σ11σ22)space and conclude this ongoing research.

Two PhD positions in Computational Mechanics and Materials Science

Submitted by nikhil.medhekar on

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.

Problems with gravity loads

Submitted by zeke2282 on

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!

I am doing research involving the finite element modeling of a human head namely Scalp, Skull, Brain & Duramater using Abaqus/CAE. I have finished modeling the parts, assigning the material properties, assembling and meshing the said model. I need to drop the whole assembly onto a 'floor'. What step should I choose. Also what interaction would I have to create so that the head would shear when it is dropped a distance less than 1 cm. Also bear in mind that it should not bounce.

 Thank you.
