Application What is Tensile Testing (ISO 6892-1)? Tensile testing is the fundamental mechanical property test that measures the behavior of metallic materials under uniaxial tensile load at ambient temperature (typically 10°C to 35°C). It determines how a material stretches and eventually breaks when pulled. This standard provides the unified method for determining key properties such

What is Fatigue Crack Growth Rate Testing (ASTM E647-15)? Fatigue crack growth rate testing, as defined by ASTM E647-15, is a standardized experimental method used to quantify the rate at which a fatigue crack extends in a metallic material under cyclic loading. Unlike total life fatigue tests (which measure cycles to failure from a smooth

This test method determines the flexural stiffness and strength properties of polymer matrix composites. Bending tests are used to determine important mechanical properties. In the test, the lower half of the laminate is subjected to tensile loads, and the upper half to compressive loads. The load is zero in the mid-plane of the laminate. Furthermore, in-plane

The interlaminar shear strength of brittle matrix laminates (such as epoxy resin matrices) is typically determined using the short beam shear test (SBS). The test principle is based on the shear stress generated during bending. If the support span

What is Strain-Controlled Fatigue Testing? ASTM E606 defines strain-controlled fatigue testing. It is a specialized mechanical evaluation method designed to determine the fatigue properties of nominally homogeneous materials under conditions where cyclic plastic strain is the dominant damage mechanism. Unlike stress-controlled (load-controlled) fatigue testing (ASTM E466), which is typical for high-cycle fatigue (>10^5 cycles), strain-controlled

What is Metallic Foil Tension Testing? Metallic foil tension testing, as defined by ASTM E345, is a specialized mechanical evaluation method designed to determine the strength and ductility of metallic materials in very thin gauges (less than 0.006 in. or 0.150 mm). Unlike standard tensile tests for bulk materials (ASTM E8), this standard addresses the

What is Extensometer System Verification? Extensometer system verification, as defined by ASTM E83-10a, is the standardized procedure for determining the accuracy and classifying the performance of devices used to measure strain (change in length) during tensile or compressive testing. Unlike force verification which checks the load cell, this practice focuses on the “strain measurement” chain,
