Engineers have long used stress-strain curves to uncover a host of material properties. The curves are created by plotting the results of tensile strength tests of material samples, putting stress ...

What is a Tensile Test? A tensile test pulls (or stretches) a sample and, as a result, the extensibility/elongation and tensile strength properties are measured in ...

A neck is formed in a tensile test specimen when the UTS of the engineering stress/strain curve is reached. Prior to this stress-strain condition the plastic deformation occurs throughout the sample ...

Plastometrex develops ASTM Standard for PIP testing, giving engineers and researchers a trusted route to cost-effective ...

Plastometrex announced that its ASTM E3499-25 for Profilometry-based Indentation Plastometry (PIP) standard has been approved.

Dynamic drop testing ensures reliable material characterisation for polymers, composites, & safety-critical applications ...

The entire stress-strain curve can now be determined using nanoindentation with a flat-ended cylindrical punch and novel analysis of the resulting force-displacement data 1. Unlike pyramidal indenters ...

Because of their very large molecular weight (~ 10 6) polymers behave differently from the low molecular weight metals during plastic deformation leading to a ductile fracture. The top diagram shows a ...

Babcock and Plastometrex support Project TAMPA using PIP technology, a physics-based approach that extracts stress-strain curves.

Spider silk has attracted the attention of many scientists because of its desirable physical properties. Most of this attention has been devoted to dragline silk, a thread that has high tensile ...
