Hi,
I am using Abaqus/CAE to model the elastic behaviour of a plate. I would like to give/define a function to prescribe the displacement along one boundary, but Abaqus does not seem to accept this the way I'm doing it*. Can anyone help me out?
* on the Load module, I choose create boundary condition > displacement, then I select a boundary, select distribution user defined, and on u1 i type "x". I then get a message saying this is not accepted.
A polymer network can imbibe water from environment and swell to an equilibrium state. If the equilibrium is reached when the network is subject to external mechanical constraint, the deformation of the network is typically anisotropic, and the concentration of water inhomogeneous. Such an equilibrium state in a network constrained by a hard core is modeled here with a nonlinear differential equation. The presence of the hard core markedly reduces the concentration of water near the interface and causes high stresses.
what is the need to model a dynamic system , like a structure under vibration (consider), by using mass and spring model only is there any alternative way of doing i think we can do it by using electronic filters , but not so deep idea i have about that, so this is my research work , i wanted to clarify this big uestion of mine as soon as possible.
Hydrogels have enormous potential for making adaptive structures in response to diverse stimuli. In a structure demonstrated recently, for example, nanoscale rods of silicon were embedded vertically in a swollen hydrogel, and the rods tilted by a large angle in response to a drying environment (Sidorenko, et al., Science 315, 487, 2007). Here we describe a model to show that this behavior corresponds to a bifurcation at a critical humidity, analogous to a phase transition of the second kind.

Dear Friends
I wanna model the blast load in abaqus/Explicit useing the subroutine "VDload"!
Could u help me to know how can I model the blast load with this subroutine?!

EPFL continues to strengthen its School of Architecture, Civil and Environmental Engineering (ENAC). We are recruiting an assistant professor (tenure track) in structural engineering. In special cases, a senior faculty appointment could be considered. We are seeking exceptional candidates with a strong interest in teaching and an outstanding record of scientific accomplishments.
I had promised to talk about subversion in my post on digitizing and editing figures but never quite got around to it. A recent spate of requests about downloading Uintah reminded me of my promise. So here's the story.
