FAILURE MODE ANALYSIS OF PLASTICS COMPONENTS & PARTS
The failure mode of component sets limit to engineering design. Therefore, Failure Mode Analysis should be part
of the engineering design and manufacturing process. The two major engineering tasks in component applications
are to perform Failure Analysis (FA) and Failure Mode and Effects Analysis (FMEA)
The engineering problem solving approaches can be applied to determine failure analysis of Plastics components
used in engineering applications. However, it is important to define failure mode and failure mechanism. The failure
mode analysis effort conducted on polymer materials provides a good materials database for computer-aided
design engineers which in turn can use the information to effectively model part reliability, thus reducing the need
for complex and costly prototype testing.
FAILURE ANALYSIS (FA)
Failure analysis consists of investigations to find out how and why something failed. The four major reasons for
engineering failures are Poor design, incorrect use of material, manufacturing defects and service conditions.
Understanding the actual reason for failures is absolutely required to avoid recurrence and prevent failure in similar
component, system, structure or product. The analysis should also help with the understanding and improvement of
design, materials selection, fabrication or processing techniques, and inspection methods.
Failure analysis is for identifying and understanding the physics of the failure processes and mechanisms of failure.
Failure analysis has been in use for decades, and has resulted in considerable improvements in components
reliability and system maintainability, even with overall system complexity increased. Traditionally, failure analysis
methods have focused on laboratory testing and physical analysis of components to fully understand why
component failed. Within the last 10years, great strides have been made in failure analysis using computer-aided
