Introduction In the field of textile and flexible material testing, understanding how a material behaves under multidirectional stress is critical for predicting real-world performance. Fabrics used in apparel, medical textiles, industrial materials, and geotextiles are frequently subjected to forces that do not occur purely along a single axis. Instead, these materials often experience localized pressure and multi-directional stress , which can lead to puncture or bursting f

Arbor Press Cutting Sample Introduction In materials testing laboratories and engineering environments, many tasks require controlled compressive force to assemble components, prepare test fixtures, or install precision mechanical parts. While large automated systems such as universal testing machines handle tensile and compression testing, technicians frequently rely on smaller manual tools to prepare equipment and samples before testing begins. One of the most reliable too

ASTM D5458 measures how strongly layers of stretch wrap film cling to each other, using a 20° inclined plane and a low-force tensile tester.

This article provides a detailed, standards-driven guide to gauge length selection for video extensometers, with practical examples from ASTM D638, ASTM D412, ASTM E8, and ASTM D3039.

If you’re trying to choose between a video (non-contact) extensometer and a clip-on (contact) extensometer, the best answer depends on what you test, how often you change specimen types, your accuracy needs, your risk tolerance for damaging samples, and—very often—budget.

Selecting the correct grips for tensile testing is one of the most important — and most overlooked — decisions in any materials testing setup.
