Systems and associated methods for component design based on stress based modal assurance criterion

A non-transitory computer-readable medium having computer-executable instructions that, when executed by one or more processors, cause the one or more processors to collectively:

• access a first component design associated with a first component, wherein a first set of finite elements are associated with a volume of the first component design;
• access a second component design associated with a second component that differs from the first component, wherein a second set of finite elements are associated with a volume of the second component design;
• calculate at least one stress-based MAC value for the second component design based a comparison between nodal stresses associated with respective corner nodes of the first set of finite elements and nodal stresses associated with respective corner nodes of the second set of finite elements;
• and
• determine whether the second component design meets at least one preselected design criterion based on the at least one stress-based MAC value.

A method for evaluating fatigue for a component design comprising:

• accessing a baseline component design associated with a baseline component, wherein a baseline set of finite elements are associated with a volume of the baseline component design;
• accessing a second component design associated with a second component that differs from the baseline component, wherein a second set of finite elements are associated with a volume of the second component design;
• calculating at least one stress-based MAC value for the second component design based a comparison between nodal stresses associated with respective corner nodes of the baseline set of finite elements and nodal stresses associated with respective corner nodes of the second set of finite elements;
• and
• accepting the second component design based on the at least one stress-based MAC value meeting a preselected threshold, but rejecting the second component design in response to the at least one stress-based MAC value being below the preselected threshold.
