Automated method to determine composite material constituent properties
First Claim
1. A non-transitory machine-readable medium with instructions stored thereon, the instructions when executed operable to:
- accept a set of user input composite material properties, including;
a composite modulus in a first direction;
a composite modulus in a second direction normal to the first direction;
a composite shear modulus in a plane that includes the first direction and the second direction;
a composite Poisson ratio in a plane that includes the first direction and the second direction;
accept a user input composite microstructure; and
automatically compute adjusted material properties of all constituents of the composite material, wherein a set of consistent fixed constituent property constraints are utilized to obtain the adjusted material property.
