failure analysis

Failure analysis can be divided into complete machine failure analysis and parts and components failure analysis, and failure analysis can also be conducted according to product development stage, failure occasion and analysis purpose. The working procedure of failure analysis is usually divided into clear requirements, investigation and research, failure mechanism analysis and countermeasures. The core of failure analysis is the analysis and Revelation of failure mechanism. Failure mechanism is a physical or chemical process that leads to the failure of parts, components and materials. The inducing factors of this process are internal and external. In the study of failure mechanism, we usually start with the external inducing factors and failure forms, and then study the hidden internal factors.
