Re: [MW:14029] Speed of Tensile Test


Hi

 

The maximum stress and strain rate limits given in ASTM A370 paragraphs 11.4.1-11.4.3.

The stress or strain rate influences the value of the material strength. A faster strain rate will yield larger strength values, and conversely, slower rates of testing will produce lower values. 

However to provide a consistent testing method , an elastic loading rate of 50 ksi per minute is to be used until after strain hardening.
