ABAQUS User Material Definition

Dear
receiver

I am writing elastoplastic vumat
with abaqus commercial code. I thoroughly am expert at the definition of
constitutive equation but have a problem with the commands of the VUMAT.

For
example I have a problem with the definition of material properties such as
expansion, conductivity, coefficient of n and k at power law hardening and ….

Is
there any specific command for defining the material properties?  For example I have to use Props(nprops) for
it?

If
the answer is yes for example which props belong to the expansion and which is
for conductivity and ….

for example:

e=props(1)

xnue=props(2)

yield=props(3)

but,

alpha=props ? alpha=heat expansion

n=props ?

k=props ? 

If
there are special commands how I can use it and please kindly introduce it to
me.

Sincerely
