Next-generation, reusable hypersonic aircraft will be subjected to extreme environments that produce complex fatigue loads at high temperatures, reminiscent of the life-limiting thermal and mechanical loads present in large gas-powered land-based tur

Delamination between plies is the most common failure mode in composite laminates that can cause fiber breakage and reduction in life of the composite. Currently Mode-I interlaminar fracture toughness or critical energy release rate of a composite is

In the recent years, Cohesive Zone Models (CZMs) have gained increasing popularity for modelling the fracture process [1] and also in other applications like composite de-lamination [2] solder failures [3] in circuits, etc. This can be attributed to

Cumulative damage theory has been extended to develop a deterministic fatigue life prediction model for materials subjected to superimposed thermo-acousto-mechanical cycling. This loading profile is exhibited by particular external panels of reusable

To alleviate computational challenges in uncertainty quantification and multidisciplinary design optimization, Kriging has gained its popularity due to its high accuracy and flexibility interpolating non-linear system responses with collected data. O

In light of the combined extreme environment to which hypersonic fuselage components will be subjected, a unique test platform has been developed for evaluating materials and structures under service-like conditions. Typical ascent-cruise-descent mis

A structural hot spot was traditionally reserved to represent a region of high stress that has a high probability for premature fatigue damage. However, in this research hot spot is defined as a location that might have high probability-of-failure or

When testing for material properties, the cost and time of the tests are an important factor. It is not practical to test every possible combination of expected environmental and loading scenarios. Therefore, a set of limited data is collected based
