ISO 10113:2006 - Plastic Strain Ratio
ISO 10113:2006 specifies a method for determining the plastic strain ratio, commonly called the r-value, of flat metallic materials, typically sheet and strip. Plastic strain ratio is the ratio of the true width strain to the true thickness strain in a test piece which has been subject to uniaxial tensile stress.
To calculate the r-value a test is performed to ISO 6892 and using an axial and transverse extensomers. Where the true plastic width strain against true plastic length strain is homogeneous a single data point method can be used, with a inhomogeneous deformation a statistical method can be used. These calculations can be done automatically using Bluehill ® * or Partner software.
An ISO 10113 test is typically performed at the same time as ISO 10275, tensile strain hardening exponent.

The second generation Advanced Video Extensometer (AVE 2) utilizes patented measurement technology in the fastest, most accurate non-contacting strain measurement device commercially available. The device dramatically reduces errors from thermal and lighting variations that are common in most labs. It can easily be adapted to nearly every testing system in your lab.
