The stress wave generated by impact or dynamic load will produce significant reflection and transmission at the rock coal interface during propagation process. This effects such as tensile, superposition mutation. These lead to obvious vibration interfaces, which is a key factor leading damage failure of mass. In process underground engineering excavation, series layered masses one important factors causing geological disasters. Based on two–dimensional similar material simulation...
As a critical part of prognostics and health management (PHM), remaining useful life (RUL) prediction can provide manufacturers users with system lifetime information improve the reliability maintainable systems. Particle filters (PFs) are powerful tools for RUL because they represent uncertainty results well. However, due to lack measurement data, parameters model cannot be updated during long-term process. Additionally, complex systems, often obtained in an analytical form. In this paper,...
Solid rocket motors (SRMs) are widely used in the aerospace and missile industries. The interface debonding between propellant/insulator/case determines life of an SRM. Therefore, monitoring further locating crucial to prevent catastrophic structural failures electromechanical impedance (EMI) technique based on piezoelectric wafer transducers is a simple sensitive health (SHM) method. In this study, high-precision probabilistic imaging method EMI for SRM case–insulator proposed. method,...
Reinforced concrete (RC) bent structures are widely used in single-story industrial buildings, with a considerable portion of them located high-intensity seismic areas. Therefore, it is significant to study the performance RC column while keeping construction costs mind. To evaluate from an economic perspective, pseudo-static tests combined cost analysis were first carried out on three columns designed according different versions Chinese codes. A numerical simulation method based extended...
