Hi Everyone,

 Is is possible to account the surface hardness effect in the tensile testing specimen? If possible, how could it be acomplished?

For instance, I would like to establish the  stress strain curve for the material that used on surface hardened component. Will there be a big change if the surface hardness effect is considered on the tensile specimen?

Please throw some light in this regard.

Thanks

Dear All,

How do find the inverse of the rectangular matrix.

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?

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.

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
