Numerical and Experimental Studies of High Strain Rate Mechanical Behavior of E-Glass/Polyester Composite Laminates

Abstract

Quasi-static (∼10−3 s−1) and high strain rate (∼850 s−1) compression behavior of an E-glass/polyester composite was determined in the through-thickness and in-plane directions. In both directions, modulus and failure strength increased with increasing strain rate. Higher strain rate sensitivity for both elastic modulus and failure strength was observed in the inplane direction. A numerical model was developed to investigate the compressive deformation and fracture of an E-glass/polyester composite. Excellent agreement was demonstrated for the case of high strain rate loading. Also, the fracture geometries were successfully predicted with the numerical model.

Experimental and numerical investigation of the effect of interlayer on the damage formation in a ceramic/composite armor at a low projectile velocity

“…Element erosion is also taken into account in the material model. The material model parameters of E-glass/polyester composite were taken from the work by Tunusoglu et al 18 and are tabulated in Table 3.…”
