Last november was a memorable month for us at Matbase, we passed the milestone of 1000 visitors per day. So I guess we were not that far of when we thought it would be a good idea to make the material database we used as students during our stay at the Delft University of Technology accessable to other people. Apparently, people appreciate the easy way they can lookup the material properties and how we present the data.
