measure of the correlation of the a given DOF of two different sets of mode shapes over a number of comparable-paired mode shapes
NOTE 1 The coordinate modal assurance criterion for DOF j is defined as:
is the mode shape coefficient for DOF j for mode r of set A
is the mode shape coefficient for DOF j for mode r of set X
r is the index of the correlated mode pairs.
For example, mode shapes X and A are test and analysis mode shapes, respectively.
NOTE 2 CoMAC = 1 indicates perfect correlation.
NOTE 3 The results can be considered to be meaningful only when the CoMAC is applied to matched modes, i.e. for correlated mode pairs.
