Testing of Structures (Loading Frames)

Testing of materials research infrastructure in structural laboratory include test devices for compression and tensile tests of materials. The equipment includes devices specifically designed for testing certain materials, general-purpose compression devices, and specialized equipment constructed using measurement and loading devices shared by two other research infrastructure of the structural laboratory.
