Induction heating system

To be able to use the laser extensometer, the heating source must allow the laser to reach the test specimen. This rules out the usage of a radiation furnace since the slit that is needed for the extensometer will not give us a gas-thight chamber. Instead, we are using an induction system (5kW) with an induction … Continue reading “Induction heating system”

Non-contact strain measurement using laser

To measure the strain when the specimen is isolated is something I have put a lot of thinking to. One common method is to put an extensometer on the specimen outside the furnace. This requires long test specimens, which is a limitation and not something we want. We want something that can measure a displacement … Continue reading “Non-contact strain measurement using laser”
