  • Automated method to determine composite material constituent properties
    Patent number: 9223914
    Abstract: According to an aspect, a method includes: receiving, at a machine comprising a processor and a memory, composite material properties for a composite material to be simulated; receiving, at the machine, a composite microstructure for the composite material to be simulated; and obtaining, using the processor and the memory, a set of adjusted material properties for one or more constituents of the composite material, for use in simulating the composite material, by processing the composite material properties and the composite microstructure using fixed constituent property constraints.
    Type: Grant
    Filed: September 17, 2014
    Date of Patent: December 29, 2015
    Assignee: Autodesk, Inc.
    Inventors: Ray Fertig, Emmett Nelson, Don Robbins
  • Automated Method to Determine Composite Material Constituent Properties
    Publication number: 20150006134
    Abstract: A method of determining in situ composite material constituent properties is provided. In one example computer software is provided that automatically determines adjusted material properties or in situ properties of each constituent of a composite material. Methods shown ensure that a finite element model will consistently predict material behavior not just at one desired stress/strain state, but in all simulated states.
    Type: Application

  • Automated method to determine composite material constituent properties
    Patent number: 8868385
    Abstract: According to an aspect, a computer implemented method includes: accepting 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, and a composite Poisson ratio in a plane that includes the first direction and the second direction; accepting 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.
