  2. Failure mode and effects analysis - Wikipedia

    en.wikipedia.org/wiki/Failure_mode_and_effects...

    Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a system and their causes and effects. For each component, the failure modes and their resulting effects on the rest of the system ...

  3. Physics of failure - Wikipedia

    en.wikipedia.org/wiki/Physics_of_failure

    An approach to the design and development of reliable product to prevent failure, based on the knowledge of root cause failure mechanisms. The Physics of Failure (PoF) concept is based on the understanding of the relationships between requirements and the physical characteristics of the product and their variation in the manufacturing processes ...

  4. Failure mode, effects, and criticality analysis - Wikipedia

    en.wikipedia.org/wiki/Failure_Mode,_Effects,_and...

    The failure mode may then be charted on a criticality matrix using severity code as one axis and probability level code as the other. For quantitative assessment, modal criticality number is calculated for each failure mode of each item, and item criticality number is calculated for each item. The criticality numbers are computed using the ...

  5. Failure of electronic components - Wikipedia

    en.wikipedia.org/wiki/Failure_of_electronic...

    The best place to start is with the failure mode. This is based on the assumption that there is a particular failure mode, or range of modes, that may occur within a product. It is therefore reasonable to assume that the bond test should replicate the mode, or modes of interest. However, exact replication is not always possible.

  6. Failure modes, effects, and diagnostic analysis - Wikipedia

    en.wikipedia.org/wiki/Failure_Modes,_Effects...

    Under the functional failure mode approach, the actual functional failure modes of the product are identified during a DFMEA. During the detailed FMEDA, each component failure mode is mapped to a functional failure mode. The functional failure modes are then categorized according to product failure mode in a particular application. [13]

  7. Fail-safe - Wikipedia

    en.wikipedia.org/wiki/Fail-safe

    If and when a "fail-safe" system fails, it remains at least as safe as it was before the failure. [1] [2] Since many types of failure are possible, failure mode and effects analysis is used to examine failure situations and recommend safety design and procedures. [3] Some systems can never be made fail-safe, as continuous availability is needed.

  8. Failure cause - Wikipedia

    en.wikipedia.org/wiki/Failure_cause

    A part failure mode is the way in which a component failed "functionally" on the component level. Often a part has only a few failure modes. For example, a relay may fail to open or close contacts on demand. The failure mechanism that caused this can be of many different kinds, and often multiple factors play a role at the same time.

  9. Design review based on failure mode - Wikipedia

    en.wikipedia.org/wiki/Design_review_based_on...

    Design review based on failure mode (DRBFM) is a tool originally developed by the Toyota Motor Corporation. This tool was developed based on the philosophy that design problems occur when changes are made to existing engineering designs that have already been proven successful.
