1. A method for use in inspecting a composite structure, said method comprising:

  • generating a virtual model of the composite structure;

    defining at least one irregularity parameter;

    conducting a first simulated inspection of the virtual model with a modeling module configured to transmit at least one simulated wave towards the virtual model to provide a first non-transitory waveform data set associated with the at least one irregularity parameter, wherein the first simulated inspection is conducted using a first evaluation setting that facilitates forming the at least one simulated wave;

    producing a first image based on the first non-transitory waveform data set;

    determining whether a quality of the first image satisfies a predetermined image quality threshold that would enable inspection of the composite structure for irregularities including wrinkles; and

    using the first evaluation setting to conduct a physical inspection of the composite structure with a stimulating mechanism if the first image satisfies the predetermined image quality threshold, wherein the stimulating mechanism uses the first evaluation-setting to transmit at least one physical wave towards the composite structure to detect irregularities in the composite structure.
