Graffiti and research, a possible marriage?

The past weeks I have worked almost full time in the lab trying to make the equipment ready for low cycle fatigue testing. We have a new videoextensometer! It is a camera used for studying the sample and register the resulting strain during testing.  The camera registers the distance between two white markers of aluminum oxide. … Continue reading “Graffiti and research, a possible marriage?”

Back in the lab

We are back from Argentina and ready for lab work. The machine is now finally running again after the failure! Professor Jonsson is also doing some lab work. A picosecond laser, which will be used for cutting and processing, is being installed. More to come!  

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 2

We spent the second day at the testXpo looking at the fatigue testing machines. Vibrophore is a group of machines suitable for high-cycle fatigue testing. Some of them were extreme, like the one on the first photo below – a 1000kN machine. The second one we looked at, 50kN, is maybe more suitable for us. What … Continue reading “Zwick/Roell TestXpo day 2”
