Specifications include, but are not limited to: The Oregon Institute of Technology (“Oregon Tech”) is seeking proposals to select a vendor to provide one (1) fatigue tester machine as specified in EXHIBIT A REQUIRED SPECIFICATIONS to equip the Manufacturing and Mechanical Engineering Technology (“MMET”) Department Metals Additive Manufacturing Lab located at the Klamath Falls, Oregon campus. Fatigue Tester Specifications: 1. Ability to do static (constant load) mechanical testing in both uniaxial (tensile or compression) as well as bending modes. 2. Ability to do fatigue (cyclic load) mechanical testing in both uniaxial (tensile or compression) as well as bending modes. 3. Bending modes here refer to both 3-point bending and 4-pt bending methodologies, including the roller or pin or fixed (cantilever mode) support in each of the points. 4. Versatility to allow various fatigue analyses, such as High Cycle Fatigue (HCF), Low Cycle Fatigue (LCF), Fatigue Crack Growth Measurement (Paris Law), KIc Fracture Toughness Measurements, CTOD Fracture Toughness Module, J-integral Fracture Toughness Module. 5. Load capacity required is 100kN. Specimens (AM’ed machine components of typical high strength alloys used in aerospace/space and advanced transportation industries) will include high strength metals, such as Ti-6Al-4V and other Ti alloys, HSS (High Strength Steels), other structurally important alloys such as Ni alloys, Al alloys, composites, super alloys, but also plastics/polymers, elastomers, polymer-based composites, etc. More specifically, the fatigue tester we need should consist of: A. Mainframe: a. Dynamic and Static Load cell = 100kN b. Vertical test space 150 – 1200 mm c. High axial and lateral stiffness (column should have negligible system compliance or calibration should include zeroing of system compliance from measurements). d. Stiff, durable, and easy to maintain. e. Actuator Stroke Length min = 150 mm f. Column spacing should allow for versatility in bending mode (bending samples in 10-300 mm length). g. Safety certification EN ISO 13849-1, and EN ISO 12100. B. Test area: a. Enclosure for safe operations by Undergraduate Students (typical users). b. Hardware (fixtures, roller/pin/fixed wedges) to allow advanced fatigue analyses (HCF, LCF), Fatigue Crack Growth Measurement, as well as advanced fatigue mechanics such as KIc Fracture Toughness CTOD, J-integral ,etc. c. High resolution and accuracy displacement gage or extensometer (gage length max 5 mm). d. Hardware to allow in situ crack growth monitoring and high precision measurements. e. All hardware should be able to handle sample temperatures of -40 to 150 deg C. f. All hardware (fixtures, roller/pin/fixed wedges) should have very high stiffness (made of high stiffness steels). C.
