Robert Henry Thurston Lecture
10:00am- 12 noon, Monday, November 12
Zhigang Suo, Harvard University
Presentation Title: Soft Materials and Soft Machines
Xuanhe Zhao, of Duke University, has just accepted our invitation to be the next Editor of the iMechanica Journal Club. The Journal Club was initiated in January 2007, soon after the launch of iMechanica. A glance at the list of past Themes and Discussion Leaders gives an impression of vibrant topics and dynamic researchers at the frontier of mechanics. iMechanica is fortunate to have a succession of excellent Editors. Xuanhe is an exceptionally creative and energetic researcher: his reserch is deep and wide-ranging. We look forward to his leadership, and to many more challenging and charming Themes and Discussion Leaders.
i wana to investigate effect of crack in lamb wave propagation in composite plate in abaqus software. to this end, i have modeled a composite plate using 3Dshell defomable planar part. Also, i modeled crack using seam tool. i have problem in defining contact between two edges of crack to transmit wave through it. can anybody help me please?
Assistant Professor Nanshu Lu at the University of Texas, Austin is among the 2012 class of MIT Technology Review 35 Innovators under 35 (TR35), with the citation of "soft, flexible electronics bond to skin and even organs for better health monitoring". Since 1999, the editors of Technology Review have honored the young innovators whose inventions and research are likely to be influential for a very long time.
Congratulations on such a distinguished honor!

Hey there, I am the newbie in Ansys Modelling, and right now I have to model of 3D RC beam reinforcing by GFRP bars.
Anyone here that can give advice or placing any beneficial link to me to refer.
Thank you so much guys.
hi every one
i have problems with abaqus incrementation , now i do fill min,max and initial increment by trial and error , its not efficiency when running time is much,i will be glad if any one can help my and give me overlook of abaqus incrementation.

Professor Zhigang Suo will give the Thurston Lecture at the IMECE 2012 meeting, Houston, 10am-noon, 11/14/2012, Wednesday.
I'm modelling an impact of a rigid body with a deformable plate (shell elements) in the dynamic explicit analysis. When defining contact parameters, I can add the damping coefficient. I'd like to know what value is typical for this parameter? After some computations, I've found that 0,01...0,05 was rather good for my model. Is that a reasonable value?
hi every body:
offsetField='', offsetType=MIDDLE_SURFACE, region=Region(
mask=('[#1 ]', ), )), sectionName='Section-3', thicknessAssignment=
In the up scrip example, how can be define the "mask" for use in getsequencefrommask?
Congratulations to Professors Jan Achenbach, Zdenek Bazant, Pol Spanos, Zhigang Suo and Wei Yang for receiving the ASME awardsSubmitted by Yonggang Huang on Sun, 2012-06-24 07:06.
In addition to the ASME awards related to the Applied Mechanics Division, some prestigious society awards will be given to mechanicians at the IMECE, Houston, Texas, in November 2012.
Professor Jan Achenbach of Northwestern University will receive the ASME Medal. [ASME Medal, established in 1920, is the highest award that the Society can bestow and is to recognize “eminently distinguished engineering achievement.” Only one ASME Medal may be awarded annually.]
Hello, I would like to know under what situation will a stiffness matrix in a FEM problem become non-symmetric? Is there any good reference to this topic? Thanks.
I want to ask, does anyone know how to design vanes for unsymmetrical elbow? At least can you give me some calculation recommendations to design it? I am doing air simulation inside ductings for my final project. Thanks all
Hello, everyone! When talking about allowable stress, Safety Factor is introduced. While in offshore engineering, there are allowable stress modifier in API and material factor in NPD. So what is the difference between safety factor and allowable stress modifier or material factor? Are they used in special load conditions?
You help will be appreciated. Many thanks!
Awards will be presented at the AMD Banquet, scheduled on Tuesday, 13 November 2012, during the ASME International Mechanical Engineering Congress and Exposition, to be held in Houston, Texas, 9-15 November 2012 at the Hilton Americas and the George R. Brown Convention Center.
2012 Society Awards:
I need some help regarding the definition of initial residual stresses and plastic strains in a shell finite element (S4R) model in ABAQUS/Explicit.
I have determined the residual stress distributions and initial plastic strains and I need to assign these distributions to a given element set.
I understand I should be looking at:
*INITIAL CONDITIONS, TYPE=STRESS
ELSET_A, S11, S22, S33
I'd like to know how the computation time depends on the element number in a model (dynamic explicit analysis in Nastran). When I work with a simple model which has a rather coarse mesh the function is linear, so 10 steps with the increment 0.001 is equivalent to 100 steps with the increment 0.0001. But I don't know how this dependency will evaluate if I build a much more complex model. Maybe it will be exponential?

hi....I have one question...it is: what is the minimum weight of a water droplet pending on the roof that it will fall down....my question is this ...shall we use both ΔP and surface tension for the solution??? plz guid me....thanks
Good afternoon all,
I am doing bird strike analysis on engine fan blade,I have used lagrangian simulation for this model,very high plastic strain are coming. please suggest how to retify it and if any one have example problem of bird strike(.k file) please share it
