Course Description

This is a Spotlight Course of the Week (Expires: 1/25/2019)
057-Forensic Engineering Part B - Four Classes of Metallurgical and Mechanical Failures

This is a three-part course sequence that describes the methods commonly used to evaluate the cause(s) of metallurgical and mechanical failures, i.e., completing root-cause failure analyses (RCFA), and recommending actions to prevent recurrences. The process is often known as forensic engineering. The procedures may be applied in legal cases in which the professional engineer doing the RCFA acts as an expert witness. However, here the primary emphasis is on finding the physical cause of metallic material failures and related engineering tasks.

The three courses may be taken separately or as a group. In general, the information in the cases histories in Part C. is built on knowledge given in Parts A. and B. plus facts provided in Course 110, Corrosion Control and Tactics. Alternatively, some P.E.'s may have previous knowledge and work experience with RCFA's of metallic materials and choose less than all three courses.

Part A. describes typical steps and procedures used in a thorough RCFA, some common classes of generic issues that can cause metallic failures, and some of the typical analytical and test techniques that are used to characterize the properties of metals that have failed. Brief comparisons are described between the usual responsibilities of the failure analyst in a legal case versus his or her actions in conducting a RCFA that does not involve legal action.

Part B. describes four common classes of specific failure mechanisms that often occur in metallic part or mechanical component failures, i.e., static stress overload, mechanical fatigue, corrosion and wear. Most of these classes of failures have multiple subclasses and each is reviewed in some detail with emphasis on how these characteristics point to effective corrective actions that may be useful. The many forms of aqueous corrosion are given special attention because of the widespread occurrence and effects of this class of failures.

Part C. provides descriptions of (6) case histories of metallurgical and mechanical failures that were completed. The objective is to provide practical examples of how the RCFA procedures and knowledge of different failure mechanisms presented in Parts A. and B. plus general engineering experience might be used. Several illustrations (sketches and photomicrographs) of the details of the cases are included. Also, a short list is provided of other RCFA examples a failure analyst working with metallurgical or mechanical failures might encounter.

This is a highly technical course. it is not for engineers who desire a general overview of corrosion processes and prevention.

A very good course at an appropriate level of difficulty. I'm a metallurgist but I had to really think while taking the test. I like that.

I took the three FE courses in rapid succession - 056, 057 and 284. This course left me better prepared to serve my customers, and as a bonus, was interesting. The courses progressed in difficulty, and the instructor responded promptly to my call, and shared insight on the citations and on other real world experience. I look forward to a related course on corrosion by Gerald Davis, #110.

Very good content but the questions are not sequenced with the material and you must read the material several times. Challenging Course.

The text is organized okay, but the complexity of the subject leaves the reader feeling like the author is "rambling" at times. That made the exam a bit challenging, mostly because of the format of the questions, which were not at all obvious in many cases. But that forced me to really concentrate on the text, which isn't bad, and the resulting good score I was able to get on the first try was all the more satisfying.

The material covered is very useful for any mechanical engineer. The wording of the exam questions (and the course material) make some of them difficult to understand what is being asked (taught).

One of the better SunCam PE pdh courses. Course is focused heavily on the metallurgical component aspect of Forensic Engineering to the exclusion of all other Forensic Engineering considerations. Over 40 pages of technical reading. Course took about 6-7 hours to read and do test.

Excellent course! I have worked on Forensic Engineering cases in the past and one of the cases had a failure associated with crevice attack which is covered in this course. I wish that I had taken your course before the case because I would have saved a few hours of research. Thanks for a great course. I would really enjoy reading real-world examples of these material failures if you had any that could be included with the course.

The course was clearlyl written and very comprehensive. The only thing that would improve the course would be one or two examples of real-life cases to illustrate how the (most likely!) complicated forensic investigation(s) were done. For instance, many years ago I and a corrosion expert colleague looked into why a horizontal rectangular stainless- steel duct in a cement plant was failing; carbon steel stiffeners had been welded to the outside, scale had accumulated on the inside walls, over time several inches of "sand" had fallen from the humid air stream and collected in the bottom and vibrations from the connected fan were not dampened in any way so the duct continuously shook. Needless to say, several mechanisms were "at work", including stress concentration at the mid-level of the duct due to the sand-loading. Overall, this is a very worthwhile and very well written course!

A very difficult course for anyone who is not a metallurgist. Also, the name is misleading. You need to chnage it to Metallurgial Engineering. I take Froensic Engineering to be investigations in ligation cases and for insurance claims.

Both Part A and Part B of the Forensic Engineering are excellent courses. Very detailed and very well explained in the documentation. The test questions are very well thought out for the material presented. I like that the questions that I missed are marked up with reference back to the document for my further review. SunCam, very well done!

1. Disappointed with test grading.


SunCam response: This reviewer challenged the answers to questions 4, 13 and 24. We cannot publish his comments because they reveal the answers to those questions.
Thanks for the feedback. The author has now revised the course document and the test questions to improve the clarity
