ISO 10113 – Plastic Strain Ratio of Metallic Sheet Strip

ISO 10113 specifies a method for determining the plastic strain ratio of flat products (sheet and strip) made of metallic materials.

Test Method

This special tensile testing method per ISO 10113, is used to determine the plastic strain ratio of flat metallic sheet and strip products.

Uniaxial tensile force is applied to rectangular material specimens with reduced parallel sections or to parallel stripe rectangular specimens and the length and

width changes are measured.

For the majority of thin sheet metals, the plastic strain ratio can be calculated by the ratio of the true plastic width strain to the true plastic thickness strain up to

the maximum applied force, assuming constant volume.

ParsRos offers Electromechanical Universal Test Systems and Dynamic Servohydraulic Test Systems that are ideal for performing accurate and repeatable

monotonic tensile testing of metallic materials per ISO 10113.

Extensometry Options

ISO 10113 requires that extensometers conform to ISO 9513.

ParsRos offers a variety of extensometer types, ranging from clip-on, automatic to non-contacting optical and video extensometers, that meet or exceed

requirements  for calibration according to ISO 9513 Class 0.5 and ASTM E83 Class B1 standards.

Factors like the specimen material, shape and dimension, the requirements for test efficiency and budget need to be considered when choosing the appropriate

strain measurement solution.

*** Before conducting 10113 , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
