Evolutionary Design of Aging Tests (EDOE)

Background
Evolutionary Design of Aging Tests is the procedure used to design the experiment for accelerated aging tests of rubber materials. The procedure assumes the correction of the final design with the help of short term preliminary tests and there for it is called evolutionary design of experiment (EDOE). Procedure of EDOE consists of three stages: preliminary design, correction step (steps) and final design.
Preliminary design is constructed on the base of information about material, that is input by user in the table titled Material Information. After that user obtains Prior Test Recommendations including test temperature and two test times. Test temperature may be decreased with special button Change Prior Test Temperature. After conducting aging under conditions, that are close to the recommended ones and measuring elongation at break (ELB) , these results (including initial values for unaged samples) should be input into the table, titled Testing Results. There should be not less then 5 samples for each term of aging. The Designed Value of Elongation at Break in the table Material Information is recommended to set not less than a half of the initial value of ELB.
The correction step(s) may be required when values of ELB do not fall in the course of aging. Then it is necessary to conduct additional test at Time 3 appearing in the table Prior Test Recommendations and etc. The procedure assumes not more than three such corrections.
Since all corrections have been done, the final design can be performed. For these purposes user inputs required temperature and number of tests in the table titled Accelerated Aging Tests Design and obtains designed times. These are optimal terms for aging at this temperature and for measuring mechanical properties. Value of ELB that is close to the Designed Value of Elongation at Break will be achieved in the end of designed schedule of tests.
Installation and Application
EDOE software is a spreadsheet solution which has a form of Excel template named EDOE.XLT. It may be used under Excel version 7 (97) and higher. For installation the template unpack downloaded file EDOE.ZIP and place EDOE.XLT into Template folder
To begin application of EDOE software one have to create new XLS file based on this template and fill it with required material information. Then document should be saved as a workbook. After aging and testing of the samples this workbook should be opened again and work may be continued.
License
EDOE spreadsheet solution is a shareware software, its application is regulated by the license agreement. The Agreement and Order Form are placed in the EDOE.XLT file. Demo version has no distinction with registered one except the term of application.
