The software CORA (CORrelation and Analysis) provides an objective evaluation of time-history signals, e.g. derived from test and simulation. The software combines two independent sub-methods, a corridor rating and a cross-correlation rating. The corridor rating evaluates the fitting of a response curve into user-defined or automatically calculated corridors. The cross-correlation method evaluates phase shift, shape and area below curves. The use of both of these two sub-methods is essential because the disadvantages of each sub-method are compensated by the other method. The philosophy of this tool is to separate engineer’s knowledge from the algorithms. External parameters to adjust the algorithms are representing this knowledge. So it is possible to tune the evaluation to the specific needs of the application.
