Inaccuracies are inherent in every analysis technique. Scatter in test results are also inherent. By calibrating analysis with test data, corrections and knock down factors can be established to ensure that failure predictions produce safe and efficient structures.
Validating engineering methods is the process of comparing an analysis result with test results.
In HyperSizer, you can validate analysis methods using the same process used to perform an analysis. The only required additional step is to enter an equivalent failure load. You benefit in that all of the material and geometry data entered to perform the failure prediction is already completed and within seconds you establish the comparison.
Along with the software install is a test database containing data from published articles. HyperSizer analyses have been correlated to over four hundred tests and are provided to you as a starting point to validate methods for aircraft FAA certification. It is intended that you add in additional test data to represent your specific material system and fabrication processes.
