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,

ASTM D695 is a test method for determining the compressive properties of unreinforced and reinforced plastics. It is used in conjunction with the equivalent tensile test standard ASTM D638. What does this standard measure? ASTM D695 provides the compressive strength, compressive yield point, and modulus of a material. The standard specimen used for strength determination

ASTM D3039 is a widely used test standard for determining the tensile properties of composite materials. Composite materials are increasingly favored by the aerospace and automotive industries due to their lightweight properties and high tensile strength, and are being used to replace metals in many applications. Although there are many different types of composite materials,

What is Elevated Temperature Tension Testing (ASTM E21)? Elevated temperature tensile testing, as defined by ASTM E21, is a standardized method for determining the mechanical properties of metallic materials at temperatures above room temperature. This test is crucial for evaluating materials used in high-heat applications such as jet engines, gas turbines, nuclear reactors, and industrial

Application What is Compression Testing of Metallic Materials? Compression testing, as defined by ASTM E9, is a fundamental mechanical evaluation method used to determine the behavior of metallic materials under axial compressive loads at room temperature. Unlike tensile testing, which pulls a specimen apart, compression testing pushes the material together, causing it to shorten and

What is Tension Testing(ASTM E8/E8M)? Tension testing is the most fundamental mechanical property test used to determine how metallic materials respond to forces pulling them apart. It measures the material’s strength and ductility by applying a uniaxial tensile load until fracture. This test provides critical data for engineering design, quality control, material specification, and research

What is Force Verification of Testing Machines? Force verification, as defined by ASTM E4, is the critical calibration procedure used to determine the accuracy of the force-indicating system of universal testing machines (tensile, compression, and fatigue testers). Unlike simple “calibration” which might imply adjustment, verification is the process of comparing the machine’s indicated force against

What is ASTM A370? ASTM A370 is the primary standard practice used to determine the mechanical properties of steel products, including carbon, alloy, and stainless steels. Unlike generic testing standards (like ASTM E8 for tension), A370 is specifically tailored to the unique geometries, heat treatments, and product forms of steel (bars, shapes, forgings, wire, tubing,
