Dear Friends,
The stress-wave propagation speed is calculated using : sqrt (elastic modulus/density)
The unit of elastic modulus is GPa, and that of density is gram/cm^dim
Can anyone please tell me how I can convert the resulting value to m/s (meter/second)?
Regards
Thank you for your respone.
I calculated it. Is that correct?
number of atoms = 27000
silicon mass = 28.0855*1.66054*10^-27 Kg
1 Kg silicon = 35.6 mole
(4530*1.6*10^-19)/(27000*28.0855*1.66054*10^-27 ) = 600 KJ/Kg
600/35.6 = 16.85 KJ/mole
Dear Friends,
Could you tell me how I can convert electronvolt to joule/mole for silicon material? I want to convert 4530 ev to joule/mole for silicon.
Many thanks in advance.
Dear Friends,
I'm trying to bulid a non-ideal hcp lattice in order to use in MD simualtion. I have12 lattice basis. but 2 of them are negative values. Can anyone tell me how I can convert the negative values to positive?
