Description
Summary:A proposal was submitted to the DoD in early 1993 against a program that allows acquisition of research equipment in support of basic research underlying the technology goals of DoD. The Air Force Office of Scientific Research funded this project (Grant No. F49620-93-1-O6O7 with Dr. Walter F. Jones as Program Manager) in September 1993 to the University of Puerto Rico at Mayaguez. An opportunity such as this allowed us to upgrade our existing fatigue and fracture laboratory facility in the General Engineering Department. Most importantly, our works, as described below, over the last year and half benifitted from this improvement significantly. As the original proposal mentioned, this laboratory was equipped with some advanced instrumentations, yet it lacked basic facilities needed to do work on fatigue and fracture. So the objective with this grant was to add followings: Surface preparation facility (for CT, fatigue, and other specimens) for metallugical examinations. Micrometer slide with mounting kit for in situ monitoring fatigue crack growth with a traveling microscope. An extensometer (multiple gage) for tension/compression and low cycle fatigue tests. Calibrator for extensometer and COD gages. Grips for CT, fatigue and tension test specimens. Range cartridges (load, strain and displacement) for MTS-810 model. metallograph with quantitative microstructural characterization capability. After the proposal was approved, the AFOSR permitted us instead to get electron microscopes. (MM)
