Journal Club Theme of April 2014: Challenges and Opportunities in 3D Printing: A Mini Introduction

3D printing, or Additive Manufacturing (AM), has drawn significant attention from both general public and research community in recent years.  Although the first prototype of 3D printing (called rapid prototyping) emerged about three decades ago and has gone through significant development, the recent explosion in its popularity appears to be mainly due to intensive media reports. However, I personally feel what is truly underneath this increasing popularity is the development of 3D printing has reached a critical point where the revolutionary transition of 3D printing from a prototyping tool (which is cool but few people take it seriously) to a high fidelity manufacturing powerhouse is occurring, which will dramatically change how materials, parts, or devices are made in the future. As will be outlined below, 3D printing is a very broad concept and there are many dramatically different 3D printing technologies. In addition, 3D printing research is part of the large manufacturing research community, which consists of many extremely innovative people. Therefore, I will briefly introduce the different 3D printing technologies then comment on the challenges and potential opportunities, which I am sure will be incomplete. I hope this can lead to more in-depth discussions.

Journal of Applied Mechanics (ASME Transactions) now publishes very fast.

Journal of Applied Mechanics (JAM) received 526 submitted manuscripts in 2013.  Among them 4 are still in review.  

The average time for the 1st round of review, with the decision to accept, or reject, or revise, is 18 days.  After the 1st round of review, the average time to make the final decision is 34 days, which include both the authors' revision time and 2nd (and more) round(s) of review.

After acceptane the uneditted manuscript appears online with the assigned DOI within 48 hours.

An elastic phase field model for thermal oxidation of metals: Application to zirconia

http://www.sciencedirect.com/science/article/pii/S0927025614002031

Abstacrt: A multi-phase field model was developed for non-selective oxidation of metals which captures both the oxidation kinetics and stress generation. Phase field formulation involved a non-conserved phase field variable as the marker for the metallic substrate, oxide scale, and a fluid phase containing oxygen, and a conserved phase field variable representing the concentration of oxygen.

presenting a new method to model of metal foams

i have presented a new method for the first time to model of metal foams that subtracts stochastic cells from a desired volume and changes it to a foam.

i would like to know if there is any phd position for this?

thank u for your consideration :)

New view of DNA

Recently, the classical view of DNA as an isotropic elastic rod has been questioned. Here we model DNA as an elastic rod inlaid with fibrils, based on which we have made prediction that is in consistency with experiments. Our analysis suggests that the bending of short DNAs can be facilitated if there exists a specific structural heterogeneity.

I heard a sound in my email Inbox. It was from the editor-in-chief of Elsevier's Engineering Failure Analysis journal. I opened the email and read that my paper was accepted to be published under some conditions for revisions per peer reviewer's comments.


Mesh free coupled with FEM

Hi All

 

I would like to know , If part of our model has geometrical complexity , is it reasonable to use meshfree method for that area ? does it fasten or ease the analysis ? how to couple it with FEM ?
