| Abstract | This Invention Relates To A Method For Measuring Elastic Modulus Of A Sample Object. This Invention Also Relates To A Method For Correcting Creep Effects In The Modulus Measurement. The Error Due To Creep In The Apparent Contact Compliance Is Equal To The Ratio Of The Indenter Displacement Rate At The End Of The Load Hold To The Unloading Rate. Determination Of This Error Term And Deduction Of It From The Measured Contact Compliance Can Be Easily Done At A Low Cost By Modifying The Data Analysis Software In Any Commercial Depth-Sensing Indentation System. |
