Test Database and Reliability Analysis

The HyperSizer test database and HyperSizer reliability analysis are described together since they are highly related to each other.
Failure analyses have been validated to tests such as buckling, sandwich facesheet wrinkling, bonded joints, and composite strength. For composite strength, 130 tests are provided, including the World Wide Failure Exercises (WWFE) composite test data. This test data, as provided in the delivered database, is used for establishing correlation factors for test scatter and analysis inaccuracy. These correlation factors are then used by the HyperSizer reliability analysis (probabilistic method). The top left image is the scatter between experiment and theory, the middle image after the correlation factors are applied, and the bottom image is a resulting histogram for a composite strength failure prediction. The user can enter and store their own test data and generate these histograms automatically for driving optimum designs based on literally hundreds of different deterministic and reliability failure predictions. |
