THE HOMOGENIZED VISCOELASTIC AND RATE DEPENDENT PLASTIC MODEL FOR PLAIN WEAVE FABRIC REINFORCED POLYMER COMPOSITES

摘要

In this paper, rate dependent mechanical behavior of plain woven carbon fabric reinforced plastic composite is investigated. The polymer matrix is assumed isotropic and visco-elastic in elastic region. The visco-elastic behavior is defined as time domain Prony series. Rate-dependent behavior in plastic region is investigated by Split-Hopkinson Pressure Bar (SHPB) test. The coefficients of Prony series are obtained inductively from the SHPB test result.
