Title:

Case Study Comparisons between Static and Dynamic Back-Calculation Results

Accession Number:

01659008

Record Type:

Component

Abstract:

Two case studies are presented in which both the static and dynamic backcalculation methodologies are utilized. It is demonstrated that the results from static backcalculation may not be within the expected range even when the corresponding error is low. The challenges associated with static methodology for backcalculating the modulus of thin layers are provided through the case study examples. On the other hand, it is also demonstrated that dynamic backcalculation showed reasonable results for the thin layers. Furthermore, it is also shown that the dynamic modulus values of multiple, viscoelastic layers were successfully backcalculated from dynamic analysis. However, the correlation between the static and dynamic backcalculation results were generally poor.
