COMPOSITE ANALYSIS AND
STRUCTURAL SIZING SOFTWARE
 

Verification & Validation

HyperSizer has been verified and validated.

Verification usually takes the form of comparing to highly detailed and discretely meshed finite element models or to published results from other analytical solutions. Verification can include comparing to failure analysis loads prediction, such as buckling, but more often means comparing the detailed computed stresses and strains. There are many documents available that provide HyperSizer verification correlation.

Validation takes the form of comparing to test data. Validation includes comparing predicted strains to test strain gauges, but more often means comparing test measured damage initiation or failure load to failure analysis predicted failure load. There are many documents available that provide HyperSizer validation correlation.

HyperSizer has a built integrated database for storing test data. Delivered with the software install is hundreds of test data. This test data along with yours can be used to define correlation factors (CFs) for performing reliability analysis. Sometimes referred to as stochastic or probabilistic methods, this option provides a sound alternative to traditional deterministic analysis that relies an ultimate load factor (usually 1.5 for aerospace structures) to achieve safety. The image below is a form used to depict the test data correlation and corresponding CFs for cylindrical panel buckling.
