Analysis of Axial Damping in Segmented Constrained Layer Fibrous Composites.

Abstract

The axial damping in segmented ply specimens is compared with that of continuous ply specimens. Axial damping increases in both designs as the free-edge transverse shear becomes more important. The axial damping of segmented specimens surpasses that of the unsegmented design when small segment aspect ratios are employed. This observed trend corresponds with earlier finite element models but fails to reach magnitudes considered practically important. Theories are presented concerning the role of damping mechanisms and techniques are suggested for improving axial damping without segmenting the plies. (MM)
