DYNAMICS
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.
Drying-induced bifurcation in a hydrogel-actuated nanostructure
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.
Subroutine "VDload"
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?!

the properties of guardrail
good evening, all iMechanica user.
do u have a properties of w- beam guardrail or we also can call is a W beam barrier?
or everybody know which website can find an information about this?
Please reply me if you are know, because i need it to do an analysis by using ABAQUS.
Thanks first. Arigatou gozaimasu. xie xie!
On geometric discretization of elasticity
This paper presents a geometric discretization of elasticity when
the ambient space is Euclidean. This theory is built on ideas from
algebraic topology, exterior calculus and the recent developments
of discrete exterior calculus. We first review some geometric
ideas in continuum mechanics and show how constitutive equations
of linearized elasticity, similar to those of electromagnetism,
can be written in terms of a material Hodge star operator. In the
discrete theory presented in this paper, instead of referring to
Non Local Model Vs Implicit Gradient Model
Hi All :
I was wondering why some people prefer to use Non Local Model while some others use Implicit Gradient Model (which can be derived from Non Local Model) .
When implicit Gradient Model is itself derived from Non Local Model ,and its FE implimentation just involves an additional average to be calculated and what is the need to introduce gradient terms ??
Thanks Alot
