| Summary: | 碩士 === 國立中央大學 === 土木工程研究所 === 100 === This research presented analytical solution and numerical simulation to quantify the uncertainty of volumetric fraction (Vf) estimates in a heterogeneous material using 2-D probes. The analytical solution was derived based upon the concept of representative volume element (RVE).The numerical simulation was used random model to determine the uncertainty of volumetric fraction. The results show that the uncertainties of the estimates depend upon the size of blocks, measurement area, and volumetric fraction. Finally, using case of terrazzo tiles application examples to compare the analytical solution and numerical simulation at the end.
