Subject: Cracks & Failure Analysis Cracks & Failure AnalysisIn many industries it is extremely difficult to manufacture products that will be totally immune to cracking and breaking in service, making testing at the point of manufacture, and during use, essential. Cracks can occur in a number of materials such as metals, composites, plastics and minerals, and may indicate manufacturing failure in industries including automotive, aerospace, building, engineering and manufacturing. Non-destructive crack evaluation is essential for quality control and ultimate failure analysis. Timely assessments are needed during production and throughout service to establish whether damage has occurred, If so, the investigator will then need to know where the initiation came through why the fault is there (e.g. a visible casting error or contamination), the size of the crack and the distance from point to point. More commonly, cracks and structural damage are identified via non-microscopic methods such as resonant frequency, piezoelectric paint sensors and ultrasound.
