Acrylonitrile-Butadine-Styrene (ABS) has been receiving much attention as a cushion against impact and vibration, on account of its very favorable mechanical properties, including elevated impact strength, stiffness and tensile strength, as well as outstanding formability. The geometry of deployed samples does influence dynamic performance. In this work, the methods of analysis, experiment and numerical computation have been applied to explore different modal parameters of rectangular ABS specimens with completely free boundary conditions. Experimentally, Pulse 15.1 software was used to investigate the modal parameters while the specimens were numerically modeled in Abaqus/Standard 3D using C3D20R (second order 20-node quadratic brick) element types with the Lancsoz Eigensolver method. Parametric explorations over the geometry space enabled useful trends to be identified with respect to vibration and impact applications. Experimental and numerical results were found to compare very favorably. Copyright © 2013 by ASME.
