Starting up the rig after failure

A few weeks ago the testing in our corrosion-fatigue rig did not go well. The machine somehow went into position control instead of load control, which resulted in the stroke moving upwards. This put a lot of load on the test specimen and the chamber, which then both broke.  We had to repair the induction coil. … Continue reading “Starting up the rig after failure”

Zwick/Roell TestXpo day 1

We were invited to the Zwick/Roell TestXpo (23rd International Forum for Materials Testing) in Ulm to give a lecture about our lab. I talked about the design of our corrosion-fatigue test rig and shared some problems we had while building it. It was very nice to see the large interest in our rig. Around 800 … Continue reading “Zwick/Roell TestXpo day 1”

Have we bitten off more than we can chew?

Today is the official start of the project with Scania. Corrosion fatigue testing in temperatures up to 1000 degrees couldn’t be so hard, could it? Well, the answer is yes. Our plan was to perform the tests at a test institute and focus on the post-analysis here at KTH. It turned out that no one could … Continue reading “Have we bitten off more than we can chew?”
