Abstract
Methods of determining corrosion of an object that occurs over a time period. The methods determine physical factors of the object and environmental factors that occur during the time period. Node points are determined on the object. At different times during the time period, the methods determine the corrosion of the object at the node points based on the physical factors and the environmental factors. A cumulative corrosion of the object is determined based on the corrosion determined at each of the node points at each of the times.
Claims20
A method of determining corrosion of an object that occurs over a time period, the method comprising:
- determining at least one physical factor of the object;
- determining a surface geometry of the object;
- determining a plurality of points on the surface geometry of the object;
- determining at least one environmental factor that occurs during the time period;
- at a plurality of times during the time period, determining the corrosion of the object at the points based on the at least one physical factor and the at least one environmental factor;
- and
- determining a cumulative corrosion of the object based on the corrosion determined at each of the points at each of the plurality of times.
A method of determining corrosion of an object that occurs over a time period, the method comprising:
- determining at least one physical factor of the object;
- determining at least one environmental factor for a geographic location of the object over the time period;
- determining a surface geometry of the object including a plurality of points that are spaced apart;
- at each of a plurality of times that occur during the time period, determining corrosion at each of the plurality of points included in the surface geometry of the object based on the at least one physical factor and the at least one environmental factor for the geographic location corresponding to each of the plurality of times;
- and
- accumulating the corrosion for the plurality of times at each of the plurality of points and determining a cumulative corrosion of the object.
A computing device configured to determine corrosion of an object, the computing device comprising:
- memory circuitry that stores program instructions;
- and
- processing circuitry configured to execute the program instructions to cause the computing device to:
- receive a date range, a geographic location of the object, and an identification of the object;
- receive a material of the object;
- determine environmental factors at the geographic location during the time period at least in part by interpolation using known data;
- determine a plurality of points on a surface geometry of the object based on the identification of the object;
- determine a plurality of points on the object based on the identification of the object;
- for a plurality of times during the time period:
- determine environmental conditions at the points;
- and
- determine corrosion at the points based on the environmental conditions and the material of the object.
