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, […]
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 encountered when implementing either method in a […]
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 can have with a growing fatigue crack. Crack inspection, detection […]
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 a detectable crack during its […]
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 that are currently employed when attempting to predict the […]
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.
