Fatigue of Overhead Electrical Conductors

Submitted by Alain Cardou on

A new paper on  the OEC fatigue problem: “Determination of Early Failure Sources and Mechanisms for Al 99.7% and Al-Mg-Si Alloy Bare Conductors Used in Aerial Transmission Lines”, by S. Karabay and E. Feyzullahoglu. Paper has been accepted for publication in March 2014 in the “Engineering Failure Analysis” journal. Abstract can be found on-line:  http://dx.doi.org/10.1016/j.engfailanal.2013.12.002

Extract natural frequencies in abaqus

Submitted by Davidgc on

Hi all,

 I am new in the blog, so I would like to appologies if this post is already published.

 I am doing a research in vibracion-based health monitoring based in CFRP beams. As a part of my research, I am modeling a composite beam in abaqus and apply transient analysis on it. Before I would like to validate my model with a very simple a easy model for this reason I have elaborated this procedure:

PhD and Post-doc Positions in Computational Modelling of Structural Batteries at TU Delft

Submitted by Angelo Simone on

Applications are invited for a PhD position (four years) and a post-doctoral position (three years) in the area of computational modelling in the Computational Mechanics of Materials group of the Faculty of Civil Engineering and Geosciences at Delft University of Technology in the Netherlands.

The successful applicants will work with Dr. Angelo Simone on a project funded by the European Research Council through the ERC Consolidator grant StruBa (Computational Modelling of Structural Batteries). The positions are to commence in June 2014 or as soon as possible thereafter.

Journal Club Theme of February 2014: Energy Challenges and Mechanics

Submitted by Henry Tan on

Since James Watt, a Scottish inventor, improve the efficiency of steam engine, human civilization relies more and more on a steady supply of energy. The re-rise as an international superpower and the global energy crisis are challenging China and the world. We are at a transitional age. On the one hand, we see the technology advances in exploration and development of oil and gas, a depleting resource; and the growth in handling ageing and decommissioning. On the other hand, we see ideas and plans for new energy structure in the future.

Abaqus Standard General Contact with penetration

Submitted by chen1164 on

Dear Colleague, 

 

I am running Abaqus Examle Problems Manual 1.1.18 - The self contact on rubber gasket.  

 

I tried to convert the self contact and surface contact definition to a general contact definition. However, the rigid surface just penatrate the model like this shown below.

 

 

Left image is the result for the inp from manual. The right one is the result for compuation with general contact.

 

Does somebody here want to discuss or maybe explain this for me ?

The toughest hydrogel in the world

Submitted by Zhigang Suo on

The class started today.  I'll be teaching fracture mechanics this semester.  I'll be mostly using the class notes I wrote in 2010, but will post updated ones. 

In today's class I covered "Trouble with linear elastic theory of strength."  I have just posted updated notes of the lecture.  The new notes begin with the follwoing paragraphs.
