Metals and metal alloys compose the majority of products, components, and structural materials used in our everyday lives. When a failure occurs, a metallurgist is commonly engaged to understand a component’s failure mode and whether it caused an accident or was the result of it. Specialized equipment is typically used, including optical microscopy, scanning electron microscopy (SEM), and materials testing. The process can include understanding a product’s design specification and whether it comported to it and was manufactured properly.
Metallurgists often work closely with other engineering disciplines to understand how a product was used and the environment in which it was used - both of which can importantly impact an understanding of a failure. A common example would be engaging mechanical engineering expertise to perform stress analysis on a component using finite element analysis (FEA).
ESi has extensive lab and inspection facilities in all of our larger offices across the country. Our seven laboratories are equipped with state-of-the-art scanning electron microscopes (SEM's), and additional enhanced technical and testing capabilities.
Based on the results and findings of this multi-component failure analysis, the client was able to remedy the problems with the new machinery design by addressing the weld defect and successfully launch the new product line.
A large, heavy-lift crane collapsed resulting in three fatalities and extensive damage to the stadium and construction equipment.
United Air Lines Flight 232 crashed and broke apart during the landing attempt.
When components fracture, fatigue is often the reason. Ron Parrington walks you through the definition and types of fatigue, how to design and test for fatigue, and common fractographic features in fatigue failures.
Crane Engineering is now part of ESi -- a significant milestone in our efforts to enhance responsiveness and ensure that we can deploy the right expertise and technologies to fit the scope of a particular project.
