I want to what exactly entropy means???I know the definition and formula but still not getting the physical significance.When we say temperature we can understand and feel it.But,in case of entropy each time I read about it I don't get it.Can anybody explore it's significance in easy way so that i can understand what exactly entropy means?

Lectures on Soft Active Materials, 2nd edition

suo group research

In May 2008, I posted 3 lectures on Soft Active Materials given at UCSB. I have since given similar lectures on other occasions, but never all three at the same place. The field has been active. The lectures have been updated with new items. I’m now posting the “2nd edition” of these lectures.

Dielectric elastomers
Neutral gels
Polyelectrolyte gels
pH-sensitive gels

The slides are posted as delivered. No effort is made to eliminate repeating slides.

Hi there,

I am new to Finite element method. I would like to know if their are any books for implants, bones and their interaction.

Thank you for your consideration.

Modeling of viscoelastic material in ANSYS

viscoelastivity

Any one can tell about the modelling of viscoelastic materials in ANSYS. In the modeeling how material properties can be given. Like I have material data in the form of Prony series parameter. If sone is having relaxation data how can that be fed to ANSYS model?

TIA

Plasticity and elasticity questions

Submitted by hiader k. mahbes on Fri, 10/23/2009 - 19:13

Dear All

I has question about these stresses.

1.Are deviatoric stress generate plastic deformation?

2. Are hydrostatic stress generate plastic deformation?

3.What is the advantage of transferring strain tenser orientation to the principle coordinate axes?

4. What is the difference between rupture and fracture stress?

Can anyone explain what is actually surface based cohesive behavior (definition and explanation).Abaqus manual doesnot explain it properly.

Modelling a composite wall in ANSYS

Non linear Buckling analysis of a composite wall

Hi,

I am doing a Non-linear Buckling Analysis of a composite wall

I am having hard time modelling the composite wall

The composite wall consists of polystyrene foam as the core element and stucco is applied on either side of the wall.

There is a thin sheet of mesh embedded in the stucco ( please see the attachment for clear visualization).

Boundary Conditions:Uniform compressive load is applied at the top surface and the bottom surface is fixed

what to calculate: Critical Buckling Load, Critical Buckling Stress
