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.

Hi All

I have just started my postgraduation in aerospace composites. I am new to FE of composites and required serious help in learning composite modelling. It will great if someone can help me in starting up. If you know any websites or books which have examples which I can go through to learn modelling of composites, please let me know. Thanks for your help.

Hi friends i am new user and 1 year experienced guy in CAE field in  Pune, India.

    i wants some tips/notes in Linear Static Analysis & non Linear analysis.

 Tips/ Notes about softwares like MSc nastran, Abaqus will be useful for me. So plz tell me how can i obtain them.

my project is life prediction of elastomer gaskets in ic engines using fea.     how can i select the constitutive model and the life prediction associated with which mechanism whther stress relaxation, stress softening or  excessive creep
