Hi all

My name is Rocío and I need some
help with composite material and Ansys program. I have done a model of part of
a bus' structure using shell 99 and I have a problem. I need to know the weight
of the models but I'm not sure where I must to introduce the density properties.
I have the density of the skin according to the volume fibre/matrix. If I
introduce it’s in the material proprieties, and apply to each ply, the model is
very heavy and if I introduce it in the real constant (in ADMUSA, dividing the
total density by the total ply numbers???) the model is very light.  Where can I introduce the density material and
how?

Thank for all.
