Investigating Cumulative Damage in a Highly Filled Polymeric Composite Material
Abstract
The effects of cyclic loading on cumulative damage, constitutive behavior, and residual strength of a highly filled polymeric composite material were investigated in this study. Uniaxial tensile specimens were used to study the accumulation of damage in the material subjected to different cyclic loading sequences. Loads, displacements, and ultra- sonic measurements made by transmitting sound waves through the thickness of the specimens were recorded during the tests. The recorded data were analyzed to determine the stress-strain curves and the relative acoustic attenuation coefficient DELTA alpha, which was used as a damage parameter of the determination of damage state of the material. The effects of different cyclic loading sequences on the material behavior of the highly filled polymeric material were discussed.
