Analysis of Dynamic Mechanical Properties for Simply Supported Beam Including ESP Glass
Institute of Electronic Engineering, China Academy of Engineering Physics, Mianyang, Sichuan, China
There is growing awareness of the need to protect system circuit from the abnormal impact loading environment. Impact mechanical sensor can immediately hold back system circuit in the extreme environment. Especially, mechanical response component of it must possess the characteristics of high fracture strength and high Weibull modulus simultaneously. Engineered stress profiles glass (ESP glass) is the best choice for achieving these two performances in all kinds of material. In many cases, it is desirable that once the impact mechanical sensor has served its function that ESP glass then fractures into very small fragments. ESP glass with controlled static fracture properties so far has been carried out theoretically and experimentally, whereas impact properties of it are rarely performed. In order to understand mechanical properties of ESP glass under impact loading environment, the mechanical behavior of the simply supported beam including ESP glass is investigated by theoretical formulae and finite element method (FEM) simulation in this paper. The theoretical computational results of the dynamic flexural strength of ESP glass are consistent with the simulation results of it. Results gained show that the relation between static mechanical properties and dynamic mechanical properties of ESP glass can be established by dynamic coefficient.
