MEE’s Response to Covoid 19

posted March 2020

The Covoid-19 pandemic has created an unprecedented disruption to everyone’s sense of normal.Throughout the past few weeks, we have been continuously monitoring the news and CDC recommendations for protecting the health and safety of our staff and any visitors to the facility.We remain open at this time with strict cleaning and safety measures implemented at our facility following CDC and MN Department of Health guidelines. Engineers have been working from home when possible, and laboratory staff are on staggered shifts to maintain social distancing while in the facility. Our commitment to providing the highest quality professional services to our clients has not changed. We are available to assist you with your product issues and concerns. If you have questions, do not hesitate to contact us.

Dick Kielty

It is with deep sadness that we share the news that friend and past employee of MEE, Dick Kielty, passed away this week. 

For nearly his entire career, Dick worked Twin City Testing (now Element) providing metallurgical engineering consulting services to local industries.  He retired from Element but was he was not the retiring kind of engineer. Dick began working for MEE at age 73. His intent was to work part time with us for two years but two years turned into eight years and he officially retired at age 81.  We so enjoyed having him around that he remained on our staff email list and would join us at staff lunches after his retirement.

His technical expertise and years of experience were valuable assets to our team. He was a great mentor to the other engineers on staff and enjoyed sharing his knowledge whether it was done one on one or presenting staff training lectures. I think all of us in the materials science and engineering fields can agree that Dick was the role model as someone who was truly dedicated to the profession.

Nitinol Seminar

Kurt Schenk and Neal Hanke, P.E.

Kurt Schenk and Neal Hanke attended a one day seminar about Nitinol and how its unique properties apply to medical devices and designs. The primary topics for the seminar included structure, processing, mechanical properties, corrosion behavior, and fatigue life of Nitinol. MEE has been helping medical device manufacturers to successfully use Nitinol in their products for almost 25 years. Even with years of experience, MEE staff continually seeks out educational opportunities to keep up with the latest research on this intriguing material.

Welcome to MEE’s new intern, Kelsy Holtgrewe.  Kelsy received her Bachelor’s in Metallurgical Engineering from Missouri University of Science and Technology in December. She’ll be starting work toward a Master’s at Colorado School of Mines this fall. She has previous work experience in the materials labs of two large industrial companies so she is familiar with many of the processes and procedures in our metallographic and SEM labs.

MEE understands that internship programs are beneficial to both the student and the company.  Our busy materials science laboratories will provide Kelsy with a valuable real-world engineering experience this summer and our technical staff appreciates the opportunity to mentor new professionals in the field of metallurgical engineering.

Congratulations to MEE Associate Engineer, Henry Ahrenholtz, who recently passed the Fundamentals of Engineering (FE) exam certifying him as an Engineer in Training (E.I.T.). The FE exam is the first of two exams required for obtaining a Professional Engineer license. Prior to taking the second exam, E.I.T’s must complete four years of qualifying engineering experience under the supervision of a professional engineer. We look forward to working with Henry as he moves forward towards professional licensure.

Larry Hanke and Dan Grice will be presenting a talk on A Historical Perspective of Fracture Analysis at the February 19 ASM Symposium at Hennepin Technical College.  The theme of the symposium is “Materials Retrospect: 100 Years of Advancement” in recognition of the 100th anniversary of the MN chapter of ASM International. Other presentations at the event will cover topics such as advancements in the casting industry, metal additive manufacturing and breakthroughs in nitinol in medical device design.

Larry and Dan’s presention will review the history of fractography, including the historical development of the science, changes in the analytical tools, and some historical case histories.
The effective use of materials in various engineering applications requires an understanding of material properties, including conditions of material failure. Fracture is behavior that must be taken into account. The study of fractures over the years has had an important role in materials engineering to improve product performance and reliability.

Twenty years ago, MEE Lab Manager, Kurt Schenk, figured out a way to capture the beauty of a freshly fallen snowflake with an SEM. Those images and hundreds of others taken over the years in our laboratory have been saved in a file on our network simply called “cool images”.

Five years ago, we thought it would be fun to share some of our favorite cool images on social media and the MEE Facebook page was created. We have since posted over 180 images. Some are just-for-fun, like snowflakes, insects and even the grooves in an LP, but most of the images are the kind of things we observe in our daily work. We have posted images that highlight fracture mechanisms, unique microstructures and particular imaging techniques used to gather critical data needed in a failure analysis investigation.

Forensic Engineering

posted January 2020

Larry Hanke, P.E.  is currently attending the NAFE 2020 conference in San Diego. NAFE, The National Academy of Forensic Engineers, brings together professional engineers having qualifications and expertise as practicing forensic engineers to further their continuing education and promote high standards of professional ethics and excellence of practice.

Materials engineering is often an integral aspect of forensic engineering investigations. For more information on forensic engineering and materials laboratory examinations visit the MEE website or view our latest newsletter.

MEE recently played host to engineering students from the University of St Thomas School of Engineering for instructional tours of our laboratories.  The students spent time with members of our engineering staff in our SEM and the Visual Inspection Labs.

We have been providing these mini-classroom opportunities in collaboration with School of Engineering’s faculty member, Dr Genevieve Gagnon, for quite a few years now.  Dr. Gagnon and MEE CEO, Larry Hanke, share a common goal of creating an educational bridge between academia and industry.

In a recent Twin Cities Business Magazine article, Plymouth MN was described as a Med-Tech Mecca.  We recognized this almost 25 years ago when we chose to locate our company here. Materials Evaluation and Engineering, Inc. was founded to fill a local need for an independent, high-quality, materials characterization laboratory for advanced materials and critical components.   A quick check of our client list shows we have worked with 75 different companies within the city.

In a 2016 blog post we mentioned a visit from then Mayor, Kelli Slavik, as part of the city of Plymouth’s Plymouth Proud Campaign. The campaign was created to highlight the thriving and diverse Plymouth business community. We continue to value the support of the city and the local business community.
