Abstract
A computer-implemented method for repairing a structural defect includes determining a size and position of a defect within a structural element and, in accordance with a structural analysis of the defect, determining a stitching pattern that counters loss of structural integrity due to the defect. A set of holes and channels are formed in the structural element in accordance with the stitching pattern. The set of holes and channels in the structural element are filled around the defect in accordance with the stitching pattern to increase strength around the defect.
Claims14
A computer-implemented method for repairing a structural defect, comprising:
- determining a size and position of an internal defect within a structural element;
- in accordance with a structural analysis of the internal defect, determining a stitching pattern that counters loss of structural integrity due to the internal defect;
- forming a set of through holes and channels within the structural element in accordance with the stitching pattern, wherein at least one of the set of through holes is directly connected to two other of the set of through holes via respective channels;
- and
- filling the set of through holes and channels in the structural element around the internal defect in accordance with the stitching pattern to increase strength around the internal defect.
A system for repairing a structural defect, comprising:
- a hardware processor;
- and
- a memory that stores a computer program which, when executed by the hardware processor, causes the hardware processor to:
- determine a size and position of an internal defect within a structural element;
- in accordance with a structural analysis of the internal defect, determine a stitching pattern that counters loss of structural integrity due to the internal defect;
- form, with a computer controlled milling tool, a set of through holes and channels within the structural element in accordance with the stitching pattern, wherein at least one of the set of through holes is directly connected to two other of the set of through holes via respective channels;
- and
- fill, with a computer controlled filling tool, the set of through holes and channels in the structural element around the internal defect in accordance with the stitching pattern to increase strength around the internal defect.
