High Strain Rate Testing and Material Modeling of an Anisotropic Glass Fiber Filled Polyetherimide

High strength composite polymers are often used in applications that require high impact strength and durability. Accurately characterizing the mechanical behavior for FE simulation requires testing the materials at high strain rates and may require multiple loading modes. Veryst Engineering has developed high-strain rate experimental facilities for testing all classes of polymers. We tested 30% glass-fiber filled Polyetherimide (PEI) at engineering strain rates from 1 x 10-3 to 1.2 x 10+3 s-1 in uniaxial tension and compression.
