System for analysis of a repair for a structure

A method of producing a generic repair component for a repair for a structure including component parts, the method comprising:

• identifying a plurality of component parts of the structure that have common material properties and common geometric constraints, and that are identified from a lay-up design of the structure;
• determining a generic repair component for the plurality of the component parts to repair the plurality of the component parts, the generic repair component having the common material properties and the common geometric constraints;
• and for a component part of the plurality of component parts,
• determining a second generic repair component includes:
• determining a material property or a geometric constraint having a negative impact on the margin of safety;
• and determining the second generic repair component having the common material properties and the common geometric constraints, excluding the material property or the geometric constraint having the negative impact on the margin of safety, the second generic repair component being different from the first generic repair component;
• extracting a set of loads from a loads model of the structure, the loads model representing the structure in an undamaged state;
• redistributing the set of extracted loads using a loads redistribution model in which a representation of a damaged or defective portion of the component part is replaced or coupled with a representation of the generic repair component, the set of extracted loads thereby being a set of redistributed loads that indicate loading incurred by the generic repair component under external loads applied to the loads model;
• performing an analysis using the set of redistributed loads to determine a margin of safety for the generic repair component under the set of extracted loads;
• and in at least one instance in which the margin of safety is positive, outputting the common material properties and geometric constraints of the generic repair component of the at least one instance to a fabrication system for production thereof, the generic repair component being suitable for repairing the component part;
• and producing the generic repair component by the fabrication system before repairing the component part.

A computer-readable storage medium for analysis of a repair for a structure including component parts, the computer-readable storage medium having computer-readable program code stored therein that, in response to execution by a processor, cause an apparatus to at least:

• identify a plurality of component parts of the structure that have common material properties and common geometric constraints, and that are identified from a lay-up design of the structure;
• determine a generic repair component for the plurality of the component parts to repair the plurality of the component parts, the generic repair component having the common material properties and the common geometric constraints;
• and for a component part of the plurality of component parts,
• determine a second generic repair component includes being caused to at least:
• determine a material property or a geometric constraint having a negative impact on the margin of safety;
• and determine the second generic repair component having the common material properties and the common geometric constraints, excluding the material property or the geometric constraint having the negative impact on the margin of safety, the second generic repair component being different from the first generic repair component;
• extract a set of loads from a loads model of the structure, the loads model representing the structure in an undamaged state;
• redistribute the set of extracted loads using a loads redistribution model in which a representation of a damaged or defective portion of the component part is replaced or coupled with a representation of the generic repair component, the set of extracted loads thereby being a set of redistributed loads that indicate loading incurred by the generic repair component under external loads applied to the loads model;
• perform an analysis using the set of redistributed loads to determine a margin of safety for the generic repair component under the set of extracted loads;
• and in at least one instance in which the margin of safety is positive,
• output the common material properties and geometric constraints of the generic repair component of the at least one instance to a fabrication system for production thereof, the generic repair component being suitable for repairing the component part.
