Axial extensometer slippage - sudden drops in strain measurement - is often misdiagnosed in tensile testing. This tech note distinguishes true slippage from other common curve anomalies and explains...

Lap shear testing requires precise measurement of displacement and strain across bonded joints. This technical note outlines best practices for selecting and deploying extensometers in lap shear...

This technical note explains two critical parameters for selecting extensometers: gauge length, the distance between initial measuring points on a specimen, and measuring range, the extensometer's...

An extensometer is a precision instrument used in materials testing to measure strain, extension, compression, or shear deformation of a test specimen under applied force. Extensometers measure...
