as you can see in attached, my model has been included too many small area, on the other hand hydrostatic and hydro dynamic pressure are gradient loads, so how we can apply these loads on inside and outside of shell plates as gradient loads?
There are several exact relations from the theory of composites that can be used to determine whether a new numerical or analytical approach gives reasonable answers. Here's a paper on some exact relations that I wrote up a long time ago and just recently posted on Scribd.
Most of you have heard about the commissioning of the Large Hadron Colider (LHC) by CERN and then the explosion of Helium followed by a postponement of operation until spring next year. One of the worries some people had was that a mini black hole would be created by the collsions. Also, the anthropic principle in one of its forms suggests that every possible universe exists but we see only our universe because it's the one in which intelligent observers exist.
I have developed a set of simple and highly accurate two dimensional finite elements for the analysis of laminated composite structures. These elements are capable of accurately predicting three dimensional stress state (all six stresses) using constitutive law. These elements reduce modeling effort, computational time and increase solution accuracy.
Can someone suggest me a proper source to support my research financially?

The Faculty of Engineering of the University of Porto (FEUP), with the support of ECCOMAS, invites you to participate in the fourth edition of the international conference Smart Structures and Materials (SMART’09), that will be held at the Campus of FEUP, at the city of Porto, Portugal, from July 13-15, 2009 (www.fe.up.pt/~smart09).
The cytoskeleton provides the mechanical scaffold and maintains the integrity of cells. It is usually believed that one type of cytoskeleton biopolymer, microtubules, bear compressive force. In vitro experiments found that isolated microtubules may form an Euler buckling pattern with a long wavelength for very small compressive force. This, however, does not agree with in vivo experiments where microtubules buckle with short-wavelength. In order to understand the structural role of microtubules in vivo, we (Jiaping Zhang and Hanqing Jiang) developed a mechanics model to study microtubule buckling supported by cytoplasm. We found that the ability for a cell to sustain compressive force does not solely rely on mic
A gel is an aggregate of polymers and solvent molecules. The polymers crosslink into a three-dimensional network by strong chemical bonds, and enable the gel to retain its shape after a large deformation. The solvent molecules, however, interact among themselves and with the network by weak physical bonds, and enable the gel to be a conduit of mass transport. The time-dependent concurrent process of large deformation and mass transport is studied by developing a finite element method.
Hi I am new to this blog as well as new to Viscoelasticity. I have some basic quiries on viscoelasticity...as I am beginner to this area.
I am working on a polymer viscoelastic fluid filled with abrasive (Silicon carbide particles) for finishing of metal surfaces.This composition (polymer viscoelastic fluid + abrasive particles) placed in a cylinder and pushed through the hollow cylinderical workpiece with certain extrusion pressure excerted by piston. Due to piston pressure, the abrasives in the composition will abrade the workpiece surface.
I am analyzing a steel thin walled cylidrical shell subjected to axial compression against buckling.I performed both eigen value linear and nonlinear buckling analyses using ANSYS.The buckling load is less than the material yield limit and is therefore elastic buckling.
One of my colleague argues that the shell will regain its original shape after the buckling load is removed,as its is elastic buckling.My plea is that the shell has passed the limit point (buckling load) and it is global buckling and no shape recovery will occur after the load removal.
