Abstract
The study presents the results of analysis of the laminated glasses composites dynamic state under impact loading. The paper investigates modelling of a rigid ball drop on laminated glasses with different thicknesses of polyvinyl butyral (PVB) interlayers. The aim of the paper is to study the dependence of laminated glasses dynamic deformation on the velocity of free ball fall. The study performs computations using a finite element method (FEM) in modern computer-aided engineering (CAE) software within a 3D modelling and explicit dynamics approach. The investigation includes a mesh-size convergence analysis. The work carries out the dynamic strains and stress state analysis in laminated glasses under different loading conditions.
