AMMRC Automated Stress-Strain Data Analysis, Storage, and Retrieval. Part 2: Data Bank Entry and Retrieval Procedures.

摘要

As part of an in-house effort to improve physical standards and tolerances for materiel through the improvement of acceptance/rejection criteria we have developed a procedure for computer processing, storage, and retrieval of mechanical properties data. This second report of a three-part series describes a computer data bank of stress-strain data and the procedures used to access the data and to update the computer-stored data files. The data bank may be accessed through graphics or teletype remote terminals. User instructions for accessing the data are given, various selective retrieval options for the available material/alloy categories are presented, and various optional tabular listings from graphics and teletype terminals are also described. The retrieval program also includes an option for obtaining a graphical display of up to three stress-strain curves on the screen of a graphics terminal and a sample set of curves is shown. The simple updating procedures for the data bank are also described. Procedures for reducing and analyzing the test data are given in AMMRC TR 79-16, which is Part 1 of the three-part series of reports. FORTRAN listings of all the computer programs used for data reduction, analysis, storage, and retrieval are given in AMMRC TR 79-18, which is Part 3. (Author)
