Modeling frequency- and temperature-dependent longitudinal dynamic behavior of linear viscoelastic, thermorheologically complex long fiber composites

Research output: Contribution to conferencePaper

Abstract

An approach to modeling the longitudinal dynamic behavior of unidirectional long fiber composites made from constituents having frequency- and temperature-dependent material properties is described. In this approach, the total displacement field is considered to be comprised of an elastic part and anelastic part. Distinct anelastic displacement fields are initially associated with the constituent fiber and matrix materials. Because the materials have different temperature shift functions, the resulting composite is thermorheologically complex. The determination of frequency- and temperature-dependent composite modulus and damping properties from corresponding constituent properties is illustrated.
