Cosmosworks With Anisotopric Material
Cosmosworks With Anisotopric Material
(OP)
Can cosmosworks analyze anisotropic material? I am trying to analyze a part made of fiberglass, and I want to see if Cosmosworks is worth buying for this.

IE: E(sum //)= f(fibre)*E(fibre)+f(matrix)*E(matrix)
thats the general formula for the law of mixtures which governs the modulus of composites in the // direction.
E(sum -|) = f(fibre)/E(fibre) + f(matrix)/E(matrix)
and the one governing the modulus in the -| direction.
(in the above f is the volume fraction)
I think that the trouble is that cosmos only allows one value of modulus. Since in a composite the modulus can change greatly btw 0 and 90 deg you need to have that taken into account. One way, since the controlling mechanisims are generally linear with applied force direction, (ie 45deg applied force has the general effect of distribution among both directions) may be defining modulus in relation to reference planes would work?

RE: Cosmosworks With Anisotopric Material
Do higher end FEA software generally allow anisotropic materials to be modeled accurately? It seems to be that by defining the Modulus as a vector so that it would have direction would work. I've never seen the general expression for the matricies used to compute the strain in the mesh. Is it possible to apply another vector quantity or is a scalar necessary. If only scaler functions can be used can the value be defined in relation to direction?
