opinion

Hi dear mechanicinas

we are here to help each other solve our problems.agree?

so why don' read others blogs?

I have written several blogs till now.but just afew people read them and just no one answer!

the  last one was"why I can't define composite layup in abaqus explicite"the error is parameter composite can not be used in abaqus explicit!

thanks

I read some textbooks about mechanics of material. regarding strain measurement with strain gauge rosette, most of them regard it as  in the plain strain status.  But in my opinion, what the strain gauge rosette located is a fress surface. In this way, the thress stress components related to this plane, that is zz, zx, zy, should be zero, assuming that  the out normal of this plane is in the direction of Z axis.  then there are sigmaxx, sigma xy, sigmayy to be measured.  Is there anything wrong with my understanding? 

 Thanks in advance. 

Hi all,
            Let me clarify first. The topic is not about imechanica.org is going away from mechanics or not.

      While we refer papers from say early 1900 to 1980's we can see a lot of fundamental developments, especially in mechanics.  In case of solid mechanics, from linear elastic solid mechanics to plasticity and non linear solid mechanics, Continuum mechanics , visco-elasticity, micro polar elasticity, finite deformation problems and a lot more .

Hi everyone,

There is a video on YouTube now of a cat using Abaqus...more specifically, the Abaqus Knee Simulator (Abaqus 6.12 release). Hope it makes you laugh:

Have a great week!

     hi, I am a student in Engineering Mechanics.  I would like to find a lab or a  professor related to fluid structure interaction(FSI) for grad study in USA.  does FSI is part of fluid mechanics discipline? or which is the right department I should search for?

     I have looked through some grad schools, I found some similary key words, such as aeroelasticity,  micro aero vehicles, swimmers, environemantl fluid mechanics, not that close anyway.

Installing
solar panels on rooftops are obviously a high risk activity. There are a number
of hazards such as working at heights which could lead to falls from heights or
falling objects. Also slippery roof surfaces, damaged roofs, electrical
discharge from uninstalled panels, electrical fitting and equipments are all
potential hazards. All these, when not properly controlled could lead to
undesired conquences.

According to the eigenstrain theory of micromechanics, described in the book by Toshio Mura (micromechanics of defects in solid, 1982) from page 15-20.

He provided the formulas for the eigenstrain at the core of screw and edge dislocation, but I can not understand completely.  

Anybody can provide some reference articles about the gradient value du(i)/dx(j) at the core of screw and edge dislocations respectively?  

 i want some one to clarify fundamental definition ,inter relationship or difference between the following terminologies .

small strain

large strain

small scale yielding

large scale yielding 

sir, need help regarding modeling of pyro ejection load where full structure is in airborne..

please help ...

I will be very grateful if anybody please guide me about the job opportunities after PhD studies in cellular mechanics in Europe or Asia. My PhD topic is Comptational simulation of mechanical tests with isolated animal cells.

Some thoughts on what to consider when reviewing the two white light techniques: http://www.nanovea.com/News/Newsletter/Apr12.html

In January 2011, the UK government announced its intention to stop
compulsory retirement for people aged 65, despite criticism of the move
by employers’ groups. Campaigners against age discrimination and unions
welcomed the change. However, official guidance makes it clear that
employers will be able to dimiss staff no longer capable of carrying out
their work. Official figures show more than two thirds of British
employers have already eliminated fixed retirement ages.

Hello all, I am having problem with one of our lens doublets getting decemented. we have been cementing this lens for many years and we did not do anything different. Recentely we start seeing this lens decementing. we use NO61 and NO65 (UV curing). Any help of how to prevent this problem from happening again will be very much appreciated.

Thank you,

Nowadays, we are talking about multiscale simulation. I am surprising that we discussed about multiscale modeling while units are still exist. In my point of view, the multiscale only be achieved if units in general equations were treated.

i want to simulate a rotating cylinder containing fluid . and this whole cylinder is also rotating about an axis which is out side the cylinder..any one can help me out?
