A destruction test based on the bridge safety appraisal is one way to verify the failure law of an actual bridge. In this paper, a stone arch bridge in a 1:10 scale model and with a span of 60 m (namely, an arch bar of the same length as the object of test) has been tested, methods of its whole test and loading process introduced, and ultimate bearing capacity, deflection and development rules ...

Failure Mode and Effect Analysis (FMEA) is one of the well-known techniques of quality management that is used for continuous improvement in product or process design. One important issue of FMEA is the determination of the risk priorities of failure modes. The purpose of this paper is to compare three different methods for prioritizing failure modes in a process FMEA study. These methods are t...

We present a relational technique to write formal specifications which not only say what the system is intended to do but also in which ways it might misbehave because of damage or other failure. For this kind of specifications we use the term failure-sensitive. Specifications are given by sets of rules out of which a complete list of failure modes for the system can be constructed. Most classi...

GaAs devices exhibit some general failure modes that can be attributed to a defined failure mechanism. The most common failure modes are observed via degradation of the MMIC parameters such as IDSS, gain, POUT, and others. The degradation observed in MMIC devices is normally a function of the material interactions and the environmental conditions during test or operation. The importance of a pa...

In this paper we focus on electromechanical modeling of high-tuning range MEMS varactors with a focus on failures caused by residual compressive stress. In particular, we quantitatively evaluate for the first time a high-tuning range parallel-plate MEMS varactor in the presence of residual compressive stress. A 3D model generated in ANSYS agrees very favorably with the measured data and explain...

When designing aerospace systems, it is essential to provide crucial failure information for failure prevention. Failure Modes and Effects types of analyses and prior engineering knowledge and experience are commonly used to to determine the potential modes of failures a product might encounter during its lifetime. When new products are being considered and designed, this knowledge and informat...

HYPOTHESIS Health care failure mode and effect analysis identifies critical processes prone to information transfer and communication failures and suggests interventions to improve these failures. DESIGN Failure mode and effect analysis. SETTING Academic research. PARTICIPANTS A multidisciplinary team consisting of surgeons, anesthetists, nurses, and a psychologist involved in various pha...

Evaluation and improvement of drug management process are essential for patient safety. The present study was performed whit the aim of assessing risk of drug management process in Women Surgery Department of QEH using HFMEA method in 2013. A mixed method was used to analyze failure modes and their effects with HFMEA. To classify failure modes; nursing errors in clinical management model, for c...

The cost of health and safety failures to UK industry is currently estimated at up to £6.5 billion per annum with the construction sector suffering unacceptably high levels of work related incidents. Better health and safety education across all skill levels in the industry is seen as an integral part of any solution. Traditional lecture-based courses often fail to re-create the dynamic realiti...
