Back in April 2015, my CW column focused on the two ASTM standardized test methods used for measuring the through-the-thickness, or interlaminar, tensile strength of composite laminates. Despite their ...
In my previous column (see “Editor's Picks,” at right), I discussed transverse flexural testing of a unidirectional composite as one method of evaluating the strength of the fiber/matrix interfacial ...
(Nanowerk News) Testing the stiffness or tensile strength of fibres in the nano to micro range experimentally, is often very time-consuming. The samples in most cases have to be affixed using adhesive ...
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 ...
Sheet metal forming operations can vary greatly in their processes. From simple bending to stretching to deep drawing of complex parts, sheet metal forming operations may take many forms. Image Credit ...
The Video Gauge noncontact extensometer from Imetrum (Bristol, UK) reportedly is the only device of its kind to achieve the exacting requirements of ISO 527-1: 2012 ASTM D638 equivalent. The system, ...
The CIEST Laboratory successfully completed testing pipe liner samples for “apparent hoop tensile strength” as described in ASTM D2290. The method uses a split disk to apply tensile forces to a hoop ...
