This
study deals with the numerical verifications of the experimentally determined
dynamic characteristics of neat Acrylonitrile-Butadiene-Styrene (ABS)
thermoplastic as well as hemp fiber particle-added ABS possessing three various
weight fractions (1%, 5%, and 10%).To this end, significant dynamic modal
parameters including natural frequencies and corresponding mode shapes have
been predicted by performing finite element analyses in Abaqus engineering
software on the rectangular plates with a dimension of 120x145mm whose one edge
is clamped and the remaining ones are completely free. Eigenvalue extraction to
estimate the first three natural frequencies and the corresponding mode shapes
of the rectangular plates has been achieved by using the Lanczos eigensolver
which is regarded as one of the most powerful methods for the solution of large
generalized eigenvalue problems. The first three natural frequencies and
corresponding mode shapes have been successfully extracted from the finite
element analyses. The predicted dynamic modal parameters have been favorably
compared to the modal test measurements. Thus, the experimental results have
been validated against the numerical predictions.
