Composite Material Failure Model Updating Approach Leveraging Nondestructive Evaluation Data

Abstract A novel failure model updating methodology is presented in this paper for composite materials. The innovation the approach found both experimental and computational methods used. Specifically, a dominant bottleneck data-driven development relates to types of data inputs that could be used calibration or updating. To address issue, nondestructive evaluation obtained while performing mechanical testing at laboratory scale are form damage metric based on series processing steps leverage raw sensing provide progressive curves then calibrate initiation point computed by full-field three-dimensional finite element simulations fiber-reinforced material take into account intra- interlayer damage. Such defined effectively monitor process, therefore, they as way modeling different length scales.
