Introduction: Probabilistic risk assessment using fault tree analysis is an effective tool to assess occurrence probability of hazardous events in chemical process industries. Unfortunately, the failure occurrence probability of the basic events are often not available in process industries. The aim of this study is how calculate basic events failure occurrence probability when basic events do ...

Background and Aims: In recent years, dental implants have received special attention in dentistry. Due to the remarkable success of predictable dental implants, there is growing interests in the scientific community from descriptions of implant success toward identify factors associated with implant failure. The purpose of this study was to identify the risk factors associated with implant f...

In this research, progressive damage of woven composite materials due to high velocity impact is investigated via finite elements method. Necessity of impact analysis of composite materials using progressive damage method is detailed and available material models for this type of analysis is discussed. Governing equations at onset of failure and failure modes as well as damage growth is express...
