Investigation on Energy Absorption Characteristics of PVB Laminated Windshield Subject to Human Head Impact
In this paper, energy absorption characteristics of PVB laminated windshield subject to human head impact are studied. SHPB method is carried out to obtain the constitutive relationships of PVB laminated glass in dynamic behavior. With the SHPB results embedded, finite element simulation is used to study the dynamic behavior of PVB laminated windshield. In particular, energy absorption characteristics are investigated. Two parameters for measuring the energy absorption property of windshield are suggested, i.e. loss of head velocity and HIC value and a parametric study is carried out to see the effect of impact velocity and impact position. Results can shed lights on the research of energy absorption capability of PVB laminated windshield.
