Using Abaqus, hanging some mass in Truss element (T3D2), facing numerical singularities and lack of convergence due to Truss elements have no initial stiffness to resist loading perpendicular to their axis. If a stress-free line of trusses is loaded perpendicular to its axis in Abaqus/Standard. Kindly suggest me how to overcome this.
Baker Hughes has an opening for a Computational Mechanics Research Engineer in The Woodlands, Texas (USA) office as described below. Please visit the Baker Hughes careers web site http://www.bakerhughes.com/careers for more details and for completing online application.
Research Studentship (PhD) in Computational Material Science: the topic is computational nano mechanics and concurrent multiscale methods for composites under impact loading.
Any one help me out ,How to estimate stiffness matrix of beam using modal experimental method?
Hi,
i'm in an internship, and i want to study the stress destribtuion with photoelasticity method, but my problem is that the material that i have is not homogenious but there ares two layers. I can do the measurement for the two material separated, but i dont know how to do that for my layared material.
anyone have an idea about how to do photoelasticity measurement for multilayere materials ?
Thanks.
Dear all,
The Significance of Alternative Energy towards Eco-Mobility Era
1st International Conference on Mechanical Engineering 2013 (ICOME 2013)
It is a pleasure to announce that the Department of Mechanical Engineering, FTI, Institut Teknologi Sepuluh Nopember, Surabaya, Indonesia is going to organize an "International Conference on Mechanical Engineering - ICOME 2013". The conference will be held on September 12-14, 2013, in Mataram, Lombok, Indonesia with its theme "The Significance of Alternative Energy Towards Eco-Mobility Era".
Hi,
I am new here and have a very basic question on the Strain Energy Density (SED) function of exponential model.
This is the exponential model SED form : W=a(e(b(I1-3))-1)
Now we have certain postulates such as that
1.W=0 when there is no deformation and
2. stress=0 when strain =0.
When there is no deformation I1=3 and hence W=0, which is correct.
Why do some strain energy density (SED) function have 1 invariant (like neo-Hookean) while some others have both 1st and 2nd invariant like mooney-rivlin? is there a specific reason behind using 1st invariant in SED vs all invariants in the SED?
