The inaugural Additive Manufacturing Benchmarks (AM-Bench) event was held last month (June 18-21) at the headquarters of the National Institute of Standards and Technology (NIST) near Washington, D.C. The benchmark tests are a set of ongoing experiments, designed to enable modelers to evaluate and [...]
In our last blog on the topic of corrosion, we discussed how corrosion control can be a “headache”, and how controlling corrosion implies controlling the man-made contributors such as corrosion fatigue, which is a very dominant corrosion factor. Nowadays, integrated computational material engineering (ICME) and recent [...]
Read Next Blog in the Series We previously discussed how corrosion can be “the good guy” for some applications when degradation is beneficial, such as in self-deteriorating medical implants. Also, how it can be “the bad guy” for some other applications where degradation [...]
A couple of months ago, there was an anniversary that might not be very well-known: July 27, 1949. It is a date as momentous for air travel as it is for the advancement of the field of fatigue and fracture mechanics. On this date, the de Havilland Comet, the [...]
Image by Praisaeng at FreeDigitalPhotos.net While plenty of industries abhor corrosion and its consequences, another sector has welcomed it as a step in the healing process: medical devices. Devices have evolved over the decades to be less-intrusive during (and after) implantation.The bio-inert nature of titanium (along with [...]
Read Next Blog in the Series Image courtesy of sakhorn38 at FreeDigitalPhotos.net The topic of corrosion makes recurring appearances in the media; it seems that when you hear about one corrosion-related problem, invariably there will be others reported-on at around the [...]
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 [...]
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 [...]
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 [...]
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, [...]
