ISO/TC 61/SC 2 Mechanical behavior
International Standard
83.080.01 Plastics in general
The proposed standard defines the general principles for determining stress-strain curves for plastics in a wide strain rate field, with a focus on data entry of material cards for finite element simulations in the event of transient loads (impact/crash). The procedure is to be used to investigate the strain rate dependent uniaxial tensile deformation behaviour of test specimens and to determine the tensile stress-strain relationship under noncyclic, highly dynamic conditions. The procedure is particularly suitable for use in the material group of injection-moulded thermoplastics, unfilled and filled, including short fiber reinforced thermoplastics with a fiber length of up to 7.5mm as well as curable plastics. The proposed standard only describes tests in a standard climate.
