Microcanonical Entropy and Mesoscale Dislocation Mechanics and Plasticity
(Journal of Elasticity, Carlson memorial Volume)
A methodology is devised to utilize the statistical mechanical entropy of an isolated, constrained atomistic system to define the dissipative driving-force and energetic fields in continuum thermomechanics. A thermodynamic model of dislocation mechanics is discussed. One outcome is a definition for the mesoscale back-stress tensor and the symmetric, polar dislocation density-dependent, Cauchy stress tensor from atomistic ingredients.
3rd ECCOMAS Thematic Conference on the Mechanical Response of Composites 2011 - Abstract Deadline Approaching
The Institute of Structural Analysis (ISD) of Leibniz Universität Hannover organizes the ECCOMAS Thematic Conference on the Mechanical Response of Composites, from 21st - 23rd September 2011, in cooperation with the Graduate School on Multiscale Methods for Interface Coupling (MUSIC) of Leibniz Universität Hannover, the German Aerospace Center (DLR), and REpower Systems AG.
EACD-3D
Has anyone worked with EACD-3D96 or EACD-3D2008(a computer program for three-dimensional earthquake analysis of concrete dams)?
I got the source FORTRAN code from NISEE, The Earthquake Engineering Online Archive, but i won't work there are some compile errors that i couldn't fix, could anyone help me on this ?
damping of wood
Hi
is damping of wood, function of frequency?
I mean the wood damping is frequency dependent or no?
if yes, any body can help me to find a reference for numerical data of wood damping as a function of frequency?
thanks alot
Soil Pile imteraction in ANSYS ASAS-NL
Hi,
In order to model a jacket supported by four piles I need to model the interaction between soil and piles in ANSYS ASAS-NL. As I want to make a trasient analysis I use ASAS-NL which unfortunately do not interact with SPLINTER. The jacket structure is modelled by 3D beam elements. Can someone tell me how I model the soil pile interaction? Is it possible to make use of P-Y and T-Z curves in ASAS-NL?
ADINA Modeling
Greetings, I have used I-Deas previously, and purchased ADINA 900 Nodes to attempt a similar project. However, I have not been able to find an answer to a simple question. Namely, I have created a parametric equation for a parabolic shell, and I would like to see it appear in the graphic window. I will post the file in a response line.
Help with Abaqus Scripting
Hi,
I am new to abaqus scripting. I need some help with accessing the odb for history output.
I have a list of odbs and i need to take the displacement and contact stresses information at the end of the step.
The syntax i tried was
import odbAccess
fileName = 'static_open_c1.odb'
stepName = 'Load'
historyRegionName = 'Node HS-1.701'
historyOutputName = 'U2'
session.odbs[fileName].steps[stepName].historyRegions[historyRegionName]
Rigid Body Dynamics. Need help.
I'm having problem with the following problem. The encircled portion of the figure is giving me trouble. I am getting confused on how to correlate it with reference frame oxyz. please help.
what is the significance of distance r for calculating angular velocity of the reference axis oxyz?
I need to find out the components of the absolute acceleration of O along ox,oy& oz.
ADINA SVEGM
I'm trying to investigate the effect of multiple support excitation (spatially varying ground motion) on seismic response of an arch dam using ADINA, so i need to apply different acceleration (and velocity and displacement) time histories on every node on structure-foundation interface.
