AIAA complete!

Posted on 04/12/2011 by jared

The trip to Denver for the AIAA’s SDM conference was great.  We got some riding in, saw some friends, enjoyed some warm weather and had some great meetings and presentations.  I thought my paper went well and had a few good questions.  I ended up giving the same talk a couple times through the week and got great feedback each time.

I was also able to catch some very interesting papers mostly on progressive damage modeling.  I am not trying to re-invent the wheel and it was great to get some insight for the upcoming rounds of my research.  More on that later!

Keep an eye out for more information on the website; it should be forthcoming.  It’s good to be home with some time to catch up on some projects that were pushed to the wayside.

Back from NAHBS; Next Stop AIAA SDM

Posted on 03/07/2011 by jwnelson97

We safely returned to the arctic feeling north after a weekend in the heat and humidity of Austin. It was a super fun weekend and we enjoyed the show. This was my first NAHBS experience and I loved the feel of the show–lots of positive energy and a true passion for everything bikes was in the air.  The highlight was Strong Frames winning the Best Carbon Bike Award.  Also, lots of fun to run into old friends and make some new ones.

The next item on the agenda is preparing for the AIAA SDM Conference in Denver next month.  I will be presenting a summary of the first round of the physical testing.  With 9 sample groups, there is no shortage of data to analyze.  The root finding is that in most cases fiber waviness and porosity reduce laminate strength in both tension and compression.  Most interesting were the large reductions in strain at failure and a seemingly small reduction in modulus of elasticity.  In short, this stuff gets me out of bed in the morning!!

Images show a strain field as captured utilizing a digital imaging correlation system and a failed tensile specimen.

NAHBS forthcoming

Posted on 02/14/2011 by jared

Anna and I decided a few weeks ago that we needed a break from the Montana Winter and decided to head to Austin for a long weekend to check out the 2011 NAHBS show.  One of the main reasons is to check out first-hand the response to Strong Frames’ carbon bike. Carl has made tremendous progress in the time we have worked together and I think he should be very proud.  It is lots of fun to work with people that are excited to learn and take the time to understand the nuances.  So if you have some time to check out his work and happen to find yourself in Austin, please stop by!  Otherwise, don’t drool too much onto your keyboard.
