ASTM D5379
Engineered in strict accordance with ASTM D5379/D5379M, our V-notched beam shear fixture (Iosipescu shear fixture) is designed to determine the shear properties of composite materials, including shear strength and shear modulus. Built with high-strength steel and featuring precision low-friction bushings, it ensures the moving half slides effortlessly along the vertical guide rod for highly accurate and repeatable results. Equipped with a locating block for quick specimen installation and available in various configurations (including high-temperature and fatigue models), it provides essential shear data for structural design, material development, and quality control in advanced composite applications.
Overview
Used with a platen on the bottom (not included), the fixture is engineered according to ASTM D5379/D5379M for tests to obtain shear property values such as shear strength and shear modulus of various reinforced composite laminates for structural designs, material development and quality control.
The testing involves a rectangular specimen where a 90-degree notch is made on both side edges in the middle section. Compression force is applied on the moving half of the fixture to generate shear stress on the notched area while strain is measured with strain gauges or video extensometers.
