Abstract
Regarding to a fiber-reinforced material formed by deforming a reinforcing material composed of a plurality of fiber layers from an initial shape and molding into a predetermined shape, an identification device, an identification method, and an identification program generate a first data in which a physical quantity distribution inside the fiber-reinforced material is mapped to the initial shape, perform binarization of the first data to generate a second data in which a label identifying the fiber layer is mapped to the initial shape, and map the second data to a predetermined shape, based on a deformation data.
Claims6
An identification device for a fiber-reinforced material formed by deforming a reinforcing material composed of a plurality of fiber layers from an initial shape and molding into a predetermined shape, including:
- a receiver configured to receive a physical quantity distribution inside the fiber-reinforced material, and
- a controller configured to identify, for a specific fiber contained in the fiber-reinforced material, which one of the plurality of fiber layers contains the specific fiber, based on the physical quantity distribution, wherein
- the controller is configured
- to generate a first data in which the physical quantity distribution is mapped to the initial shape based on a deformation data that associates the initial shape with the predetermined shape,
- to perform binarization of the first data to generate a second data in which a label identifying which one of the plurality of fiber layers contains the specific fiber is mapped to the initial shape, and
- to map the label to the predetermined shape by mapping the second data to the predetermined shape based on the deformation data, wherein the mapping of the second data enables automated identification of fiber layers in bent portions of the fiber-reinforced material.
An identification method for identifying, for a specific fiber contained in a fiber-reinforced material, which one of a plurality of fiber layers contains the specific fiber, based on a physical quantity distribution inside the fiber-reinforced material wherein the fiber-reinforced material is formed by deforming a reinforcing material composed of the plurality of fiber layers from an initial shape and molding into a predetermined shape, the method comprising:
- generating a first data in which the physical quantity distribution is mapped to the initial shape based on a deformation data that associates the initial shape with the predetermined shape,
- performing binarization of the first data to generate a second data in which a label identifying which one of the plurality of fiber layers contains the specific fiber is mapped to the initial shape, and
- mapping the label to the predetermined shape by mapping the second data to the predetermined shape based on the deformation data, wherein the mapping of the second data enables automated identification of fiber layers in bent portions of the fiber-reinforced material.
A computer program product comprising a non-transitory computer-readable storage medium storing computer instructions which, when executed by a computer, cause the computer to perform a method of identifying, for a specific fiber contained in a fiber-reinforced material, which one of a plurality of fiber layers contains the specific fiber, based on a physical quantity distribution inside the fiber-reinforced material wherein the fiber-reinforced material is formed by deforming a reinforcing material composed of the plurality of fiber layers from an initial shape and molding into a predetermined shape,
- the method comprising:
- generating a first data in which the physical quantity distribution is mapped to the initial shape based on a deformation data that associates the initial shape with the predetermined shape,
- performing binarization of the first data to generate a second data in which a label identifying which one of the plurality of fiber layers contains the specific fiber is mapped to the initial shape, and
- mapping the label to the predetermined shape by mapping the second data to the predetermined shape based on the deformation data, wherein the mapping of the second data enables automated identification of fiber layers in bent portions of the fiber-reinforced material.
