Product Reliability in the Medical Device Industry: Lab Testing Is Not Indicative of True Failure
Brentwood, TN, August 28, 2013: A recent TV commercial on medical implants caught my attention. While touting the benefits of extensive laboratory testing, the fine print said that “…results of the testing have not been proven to predict clinical wear performance…” How true. Laboratory testing is rarely indicative of true wear and does not predict actual product reliability in [...]

The Need for Speed
In the race to get products to market, does risk-mitigation get enough time in the winner’s circle? What do aerospace, medical device manufacturers, and auto racing all have in common? Answer: the need to minimize risk of premature/unexpected component failure while crossing the finish line first. While these industries each have vastly different stakeholders, goals, and success metrics, [...]
Structural Design Concepts: Safe Life, Damage Tolerance and VEXTEC’S Virtual Life Management® (VLM®)
Example Application of VPS-MICRO Over the last few weeks, VEXTEC has explored the two main philosophies of modern structural design: safe life design and damage tolerant design. Today we share with you a summary of these methods, including their benefits and limitations. We will also look at other considerations that are commonly [...]
Structural Design Concepts: Damage Tolerant Design
Read the Next Blog in the Series The damage tolerance approach to design has been employed by the aerospace industry for decades. In contrast to the safe life design method, damage tolerance explicitly accounts the fatigue crack growth process. This design approach takes advantage of the portion of service life a component [...]
Structural Design Concepts: Safe Life Design
Read Next Blog in the Series The philosophy of safe life design is the preferred method for designing components for durable operation in the automotive industry. Under this method, the structure is operated at a stress far below the fatigue strength of the component. By doing this, the designer assumes that the structure will not form [...]
Structural Design Concepts: Overview of Safe Life and Damage Tolerance
Read Next Blog in the Series Note: This post is the first in a series of blogs exploring industry-recognized structural design principles. This material originated in an internal white paper written by Dr. Robert Tryon, Chief Technology Officer at VEXTEC. In the world of structural design, there are two main analytical techniques [...]
SEQUESTERING THE NEXT GENERATION
The hottest word currently being spoken in offices and around dinner tables in the US is “sequestration.” Not since the seminal juror movie 12 Angry Men has the word enjoyed such buzz. While there are many ongoing debates concerning the political ramifications of this government budget-reduction action (that went into effect on March 1), today we would like [...]
