The sandwich composite structure model for low-velocity impact
Original language description
The contribution is focused on finite element simulation of sandwich composite structure subjected to transverse low-velocity impact. The composite structure consist of fiberglass woven composite skin and low-density foam core. The user defined material model considering non-linear elastic and damage of composite skin was implemented into Abaqus software using VUMAT subroutine. The non-linear behavior of foam core was modeled using Low-Density Foam material model. Material parameters of composite skin and foam core were determined during previous work1, 2. The experimental testing of transverse low-velocity impact was performed on sandwich composite square plate using drop test machine designed by authors. The responses of sandwich plate in form of deflections in tree selected points on the upper skin surface were measured using laser sensors. The contact force-time dependency during the impact event was obtained using the force sensor in the head of impactor. The results between the numerical model of sandwich structure square plate and experimental data were compared. The occurrence of damage was visually compared too, the impact events ware recorded using the high-speed camera.
