Laminated safety glass is used in the automobile industry and in architectural applications. Laminated safety glass consists of a plastic interlayer, such as a layer of poly vinyl butyral (PVB) or Butacite, surrounded by two adjacent glass plates as shown in Figure 1. The glass can be float glass, plate glass, tempered glass, or sheet glass, and the plastic interlayer is made of a viscoelastic ...

In order to study the trajectory deflection of projectile penetrating obliquely into different materials, Lagrange algorithm LS-DYNA was used simulate three-dimensional model. The impact angle is 70°, concrete target and soil are penetrated respectively. state target, strain nephogram stress under maximum overload obtained. curves penetration depth, velocity, energy analyzed. results show that:...

The objective of this study was to obtain a quantitative understanding of the crateting process over a broad range of conditions. Our approach was to numerically compute the evolution of impact induced flow fields and calculate the time histories of the key measures of crater geometry (e.g. depth, diameter, lip height) for 9 2 variations in planetary gravity (0 to 10 cin/s ), material strength ...

With the development of complex terminal effects, semi penetration effect annular groove projectiles on multi-layer targets has obtained increasing attention. In this paper, based theory cavity expansion, a comparative analysis model is established for oblique projectile and ogive-nosed into targets. The FEM software LS-DYNA used to simulate calculate time history curves velocity, axis deviatio...
