Hello all

I have a problem with my VDLOAD file for abaqus.

My vdload.for file is:

Rod Clifton , Rush C. Hawkins University Professor Emeritus and Professor (Research) at the School of Engineering at Brown University, has been selected as the winner of the 2013 Sigma Xi Monie A. Ferst Award .

Dear Marc specialist users Colleague:

I am developing an user material subroutine (HYPELA2) in Msc Marc (Marc Mentat2012.1.0, Windows platform, 64bit).
I am trying to make a write inside in Hypela2.f routine, but it doesn't work.
I have used the file number unit 6, for example,  write(6,*) ' Hello' , but
no any results in the standard output file. Otherwise, the Hypela2 works properly.
Does anyone have any suggestions how can I write out any data from Hypela2.f?
Thanks.

Leslie

See annoucement.  Congratulations to Professor Mary Boyce!

There are six distinguished biophysicist in cell mechanics field (their research interests cover much broader areas) and the abbreviations of their first names are either C or D. They are Dr. David Weitz (Harvard U.), Dr. Christopher Chen (U. Penn.), Dr. Dennis Discher (U. Penn.), Dr. Denis Wirtz (JHU), Dr. Douglas Robinson (JHU), and Dr. Daniel Fletcher (U.C. Berkeley). These six scientists use both experimental and theoretical approaches to investigate the biological responses of proteins and cells to mechanical stimuli, such as forces and geometrical constraints. Their research extends from molecular scale to cellular level to tissue level.

Hi.

I'm working  with the element link8 (Ansys 12.1) and I have to
introduced the tensile curve and compression curve, but I don't know,
How I have to introduced its???

I have worked with the comands: TB: aniso, miso,..., I think the best
option is: TB, user, but How I have to introduced the values of tensile
and compression curve?, when this are different.

 File attachment is the tensile and compression curve to introduce

Thank you, Toni

Today, February 7th, the NAE is announcing the election of 69 new members and 11 new foreign associates. The public announcement will be issued at 10:00 a.m. (EST) and will be posted on the NAE website.

Congratulations to Michael Ortiz and David Hibbitt!

It gives me great pleasure to announce the outcome of the inaugural competition for the Eshelby Mechanics Award for Young Faculty. This award, created in 2012, will be annually given to rapidly emerging junior faculty who exemplify the creative use and development of mechanics. The intent of the award is to promote the field of mechanics, especially among young researchers. The selection committee consisted of: K. Ravi-chandar (UT Austin), Huajian Gao (Brown University), Kaushik Bhattacharya (Caltech), Roger Fosdick (Minnesota University), and Yonggang Huang (Northwestern University).

Hello,

I am working in a fluid mechanics theme. Do anybody now something about the Radial Reynolds Number? 

Thank you. 

I would like to know a suitable way to generate meshs for fractal surfaces and export them to be used in FEM computations.

Could someone explain me what do the curvature tensor mean at surface structures?

THX for the help!

DEAR everyone :

    I want to  combine XFEM and UMAT(about concrete) in ABAQUS,I have some questions about this ,concrete is a Special materials and I have the Constitutive equation about concrete ;Can I use the new constitutive equation and  simulate mixed CONCRETE cracking by XFEM(UEL_XFEM) in ABAQUS,how to combine UEL and UMAT in abaqus, thanks in advance,or you can Recommend  some relative infomation for me  

The Journal of Applied Mechanics Award is provided by the Applied
Mechanics Division of the American Society of Mechanical Engineers to honor the
best paper which has been published in the Journal of Applied Mechanics during
the two calendar years immediately preceding the year of the award. The award
will be made annually to the corresponding author of the paper who received their
Ph.D. no more than 10 years prior to July 1 of the year of award. Corresponding
authors who have yet to receive a Ph.D. may also be considered. The award will
be presented at the AMD Banquet at the IMECE meeting.

Hi everybody,

I have some problems with the structural analysis of an drive bullwheel on Ansys.

How can I apply the load on the bullwheel groove? 

Tangential (constant) and normal components

I was thinking to apply the normal load using a prep>loads>define_loads>apply>FUNCTIONS but I'm not good at this option. Is it necessary to define a particular coordinate system?

The mesh has been done with the SOLID186. I need to introduce the ESURF for this type of load, how can I do that?

Thank you very much. I'm an student and this is my first work with Ansys. 

I am working on the vibratory simulation of engin cooling system. Now
i want to add the component of rubber isolators , the idea is to add
the spring element ,we have tested the dynamic stiffness during range
of 5-100HZ , i konw that in ANSYS we can use the matrix 27 element to define the dynamic stiffness ,but how can i set the values in abaqus or inp files.

Thanks for your helps!

It is my pleasure to announce the launch of the "Eshelby-UH Mechanics Award for Young Faculty". This award will be given annually to rapidly emerging junior faculty who exemplify the creative use and development of mechanics. The intent of the award is to promote the field of mechanics, especially among young researchers. While interdisciplinary work that bridges mechanics with physics, chemistry, biology and other disciplines is encouraged, the ideal awardee will demonstrate clear inspiration from mechanics in his/her research.

Dear All, 

Hi.

I want to model cylindrical shell that it's thickness varies from top to bottom with this function

 h=h0(1-ε cos(θ)) or each arbitrary function that is vary from top to bottom.How can I do this? 

 Please help me!!! that for my pleasure to be guided with your comments.

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.        

hi

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?
