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 (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.

Postdoctoral researcher position opening at Pohang University of Science and Technology (POSTECH), KoreaSubmitted by hariharan on Mon, 2014-04-21 22:16.
We are seeking a highly qualified candidate for a full-time postdoctoral researcher position in the area of Computational Mechanics at the Graduate Institute of Ferrous Technology (GIFT), Pohang University of Science and Technology (POSTECH), Korea. Candidates with a strong background in continuum/dislocation-based plasticity theory, computational mechanics of sheet metals, FE modelling of sheet metal forming processes… are highly encouraged to apply.
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.
I would like to know if it is possible to use TBFT option in ANSYS to curve-fit Anand's model parameters using experimental force-displacement data.
I am aware that the ANSYS manual has description for hyperelastic and even chaboche model, but is there an established procedure to obtain Anand model parameters using experimental curve fitting ?
Hi my friends!
I hope everythin's ok!
As I previously said I'm doing some researches about fully developed turbulent flow inside an annuli.Now I've faced some problems. Does anyone know how can I calculate Darcy friction factor for a fully developed turbulent regime inside an annuli not using colebrook equations and moody diagram? is there any other way?
I'd be really thankful if anyone could help me .
One research scholarship is immediately available to support a PhD
student to work on a project in Geotechnical Engineering area. The project is funded by the Australian
Research Council (ARC) and lasts 3 years.
The scholarship will provide a stipend of A$ 25,392 per annum (in
2014). Tuition waiver will be
nominated. Exceptional candidate is
eligible to be awarded an extra amount of allowance in appreciation of his (or
her) possible high quality research outcomes.
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 am doing my research in nonlinear vibration of beams. In that research, I have to derive the shape function for different end conditions of the beam. Regarding this,I need some ideas. Are there books I can reference?
Thank you for your help.
I am trying to find the rate of crack growth in steel beam under fatigue loading using ABAQUS... i am having trouble with the loading part.... How to provide cyclic loads in ABAQUS...and obtain the increment in crack length with time??? Please help
I would like to use condensation to calculate the normal modes of
a structure. These grids are connected to the structure through RBE3 (master
grid). Let me know if there's a way to use the master grids of RBE3 elements in
the error form the f06

Can any help me know about how to optimize using ABAQUS?
I am working on mode localization of composite plate, kindly help
Suganth Kannan writes writes about the inspiration behind his model for earthquake prediction – and what he learned on his (“tedious but worth it”) journey to publication
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.
I am new in using abaqus, please can any one help me with tutorials, book or anything that guide me on how to simulate failure and damage progressive in composite materials using abaqus.
Thanks you all

I'm conducting a simple shear test (single lap joint) between aluminum bonded with 3M adhesive.
Adhesive material is 3M VHB 4930 adhesive (acrylic)
Result obtains =
Load vs Displacement Curve
True Stress vs Stretch Ratio
From the literature, mostly they used Yeoh model for 3M adhesive (Modeling and simulation of dielectric elastomer actuators,M.Wissler 2005).
An exciting short course on "Extremely deformable structures" will take place at the
International Centre for Mechanical Sciences (CISM) in Udine (Italy) from June 2nd to June 6th.
I'm looking for how we can do homogenization on ABAQUS.
thank you in advance.
Je cherche comment nous pouvons faire homogénéisation sur ABAQUS.
merci à l'avance.
i would like to condense the model (superelement) using Nastran (PARAM, EXTOUT, DMIGPCH).
but, i'm having few CONM2/CELAS1/CBEAM elements at condensation locations. i would like to know these (CONM2/CELAS1/CBEAM) elements will create any issue while condensation
