Wind Tunnel Mechanical Testing Facility

Chaikin, Pine, and Thompson combine their capabilities to create a benchtop “wind tunnel” mechanical testing facility where the mechanical properties of colloidal, composite, and mineralized model systems can be measured and their scaling relationships elucidated, with the aim of developing design principles for optimizing structures. This facility enables real-time visualization of deformations as stresses are applied, fractures propagate, and materials yield. The wind tunnel facility builds on the suite of mechanical testing equipment located in the Biomaterials and Biomimetics Equipment Facility, which currently is operated as an open user facility with five full time staff researchers. The facility houses (i) a four electrodynamic mouth motion fatigue systems (Enduratec ELF-3300 – 2000 N, 2 biaxial and 2 unaxial); (ii) universal testing machine (Instron 5566 with 8000-N capability); (iii) an R-ratio uniaxial fatigue testing machine (Electro Dynamic 1,Test Resources); (iv) a universal tester (Romulus IV with hardness, shear, and break point modules); (v) a low-load uniaxial testing machine (Chatillon M3200 with micotensile fixtures), (vi) a wear tester (Sabri Oral Wear Simulation system); (vii) hardness tester (Buehler with Vickers and Knoop diamonds); and (viii) a profilometer (Mitotoyu). The Biomaterials and Biomimetics Equipment Facility also houses (i) two environmental scanning electron microscopes (Hitachi 3500N, Zeiss EV- 50), each with energy-dispersive spectroscopy (PGT IMIX) and backscatter electron imaging detectors for elemental composition and atomic density analyses; (ii) two sputter coaters (EMITECH, ISI); (iii) for X-ray imaging and x-ray diffraction, a microcomputer-aided tomography system (Skyscan 40), Faxitron x-ray machine for high-resolution planar images, and an X-ray diffraction system (Philips APD3520); (iv) for optical microscopy, a confocal microscope (Technical Instruments K2S-BIO), a portable confocal microscope (modified Technical Instruments K2S-BIO), two 3D microscopes (Edge R400 and H160 Real-Time), two fully automated compound microscopes (Leica-Leitz DMRX/E, Zeiss Photomicroscope I), both with contrast enhancements and fluorescence), a 3-D digitizer (Mitutoyo Video-Based), and state-of-the-art image analysis software, (v) for materials characterization, a Fourier transform infrared spectrometer (Nicolet 550, with IR-Plan microscope), a Hg intrusion porosity measuring system (Micromeretics Autopor 9200), a specific surface and porosity measuring system (Micromeretics Flowsorb II 2300), a thermogravimetric system (Perkin-Elmer TGS2).
