Bulge Tester

bulgetester.20080418.4809064a63cee4.11235786The unit consists of a piezoelectric actuated piston capable of 60 Hz attached to an oil chamber. A metallic film sample is suspended above the oil chamber. Oil pressure and film deflection are monitored with a pressure transducer and laser sensor respectively. The unit also has a video camera to monitor testing.

Experimental results are then combined with newly developed theories to predict properties including fracture toughness, etc.

Designed and constructed by B. Erdem Alaca, Kristopher Wehage, and Jacob Ruden

Developed by HTML, this Bulge Testing Apparatus is used to perform biaxial tests on nanoscale metallic films and polymeric substrates.
