Composite Durability Analysis via Frequency Domain Modeling

The patent creates a computational model that copies and simulates the physical behavior of composite materials under various loading conditions. Instead of conducting extensive physical coupon tests, the model replicates material responses to loads, allowing prediction of behavioral characteristics including damage initiation and progression. This virtual copying approach maintains prediction accuracy while eliminating time-consuming physical testing iterations.

The patent establishes material behavior models and damage progression rules in advance, before actual design iterations are needed. By pre-defining how composite materials respond to different loading conditions and damage states, the system enables rapid prediction during design cycles without requiring real-time or post-hoc extensive testing, thus reducing overall design time while maintaining accuracy.

The computational model serves as a virtual substitute for physical coupon testing, copying material behavior through mathematical representations rather than physical specimens. This approach maintains the ability to predict behavioral characteristics accurately while eliminating the recurring costs of material procurement, testing setup, and physical experimentation associated with traditional methods.

The patent replaces the mechanical testing system with a computational analysis system. Instead of physically loading coupon specimens and measuring responses, the system uses computational models to simulate mechanical behavior, substitute physical measurement with calculation, and replace laboratory equipment with software algorithms, thereby eliminating testing costs while preserving prediction capability.
