Testing Products for ASTM D5379
APP-D5379Shear Properties of Composites (V-Notched Beam / Iosipescu).
Application Insight:
Uses V-notch for pure shear state. Highly sensitive to notch precision.
Pro Tip:
Strain: Requires back-to-back ±45° gauges to capture shear modulus (G12) accurately.

Implementation Commentary
The Iosipescu test. Newton-Series DSP handles simultaneous processing of dual-sided gauges to calculate real-time shear strain.
Common Pitfalls
Notch Precision: Dull cutters create stress concentrations, causing tension/compression failure instead of shear.
