Abstract
A method is present for monitoring a structure. A plurality of modes is identified for a first response for the structure at a first temperature. Each mode in the plurality of modes is adjusted from the first temperature to the second temperature to form a plurality of temperature adjusted modes. A temperature adjusted response is formed from the plurality of temperature adjusted modes in which the temperature adjusted response is adjusted to a second temperature from the first temperature. The temperature adjusted response is compared to a second response to evaluate the changes in the structure between the two sets of measurements.
Claims23
A method for monitoring a structure, the method comprising:
- identifying a plurality of modes for a first response for the structure at a first temperature;
- adjusting each mode in the plurality of modes from the first temperature to a second temperature to form a plurality of temperature adjusted modes;
- forming a temperature adjusted response from the plurality of temperature adjusted modes in which the temperature adjusted response is adjusted to the second temperature from the first temperature;
- and
- comparing the temperature adjusted response to a second response obtained at the second temperature.
An apparatus comprising:
- a structure having a set of components;
- a set of transmitters physically associated with the set of components, wherein the set of transmitters is capable of sending signals into the set of components;
- a set of sensors physically associated with the set of components, wherein the set of sensors is capable of detecting a response to the signals;
- and
- a data processing system in communication with the set of transmitters and the set of sensors, wherein the data processing system is capable of identifying a plurality of modes for a first response for the structure at a first temperature;
- adjusting each mode in the plurality of modes from the first temperature to a second temperature to form a plurality of temperature adjusted modes;
- forming a temperature adjusted response from the plurality of temperature adjusted modes in which the temperature adjusted response is adjusted to the second temperature from the first temperature;
- and comparing the temperature adjusted response to a second response obtained at the second temperature.
A computer program product comprising:
- a non-transitory computer recordable storage media;
- program code on the computer readable storage media for identifying a plurality of modes for a first response for a structure at a first temperature;
- program code on the computer readable storage media for adjusting each mode in the plurality of modes from the first temperature to a second temperature to form a plurality of temperature adjusted modes;
- program code on the computer readable storage media for forming a temperature adjusted response from the plurality of temperature adjusted modes in which the temperature adjusted response is adjusted to the second temperature from the first temperature;
- and
- program code on the computer readable storage media for comparing the temperature adjusted response to a second response obtained at the second temperature.
