Background. The research deals with the study of safe laminated glass of modern cars, consisting of two layers of toughened glass bonded together with a thin layer of polyvinyl butyral (polyvinyl butyral – PVB). The subject of research is the process of deformation and fracture of laminated safety glass in modern passenger cars in a frontal collision with a dummy. The purpose of the study is to compare the descriptive capabilities of the two computer-related models of deformation and fracture of laminated safety windshields when they collide with a dummy in the range of 10 to 60 km / h and collision angles – from 0° to 30°.
Materials and methods. Study of the deformation and fracture of safe laminated glass in modern passenger
cars in case of a frontal collision with a dummy are performed on the finite elements method.
Results. Two computer models are worked out. The first computer model of a windscreen is constructed on the base of shell elements of Belychko – Tsai with six points of integration in thickness and has two points of integration for each layer. The second computer model is built on volumetric elements with a single point of integration for each layer.
Conclusions. Comparison of descriptive capabilities of the two computer models of the collision process of the dummy with the windshield of the car proved that the second computer model satisfies the requirements of the established quality representations of the process of deformation and fracture of laminated safety glass in modern passenger cars. 

Key words
