Abstract: China is actively building urban utility tunnels and incorporating gas pipes into the tunnels. However, there is a certain risk of leakage and explosion when gas enters the tunnels. If the gas pipe leaks and causes an ...

Abstract: Gas safety in a utility tunnel is an important scientific problem. In this study, explosion model tests of methane–air mixed gas were conducted to evaluate the safety of the gas. Furthermore, the influences of the concentration ...

Abstract: The goal of this study is to investigate the dynamic mechanical properties of low yield (LY) point steels (LY100, LY160, and LY225) under high strain rates and elevated temperatures. The separate Hopkinson pressure bar ...
