This blog post covers the description and determination of Young’s modulus, tangent modulus, and chord modulus. These properties, commonly used for product and material specification, can be calculated by subjecting a specimen to uniaxial force, measuring its stress and strain properties, and generating a stress-strain curve. The accuracy of the modulus determination depends on the precision of the load and strain measurements.
A Universal Testing Machine Retrofit is a system upgrade in which the capabilities and functionality of an outdated and/or broken universal testing machine are improved by pairing them with advanced indicators and replacement components. A system retrofit is commonly performed on but not limited to tensile testing systems, compression testing systems, torsion testing systems, and bend testing systems. Universal testing systems manufactured by Instron, Satec, MTS, Tinius Olsen, Baldwin, Forney, and others are all capable of being upgraded by ADMET’s retrofit service.
Choosing the most appropriate tensile grips to effectively secure your samples is critical in getting accurate measurements of tensile properties such as tensile strength, peak load, elongation, tensile modulus, and yield.
Materials Testing is that part of engineering design, development and research that relies on laboratory testing of one kind or another to answer questions. Testing is also required during manufacturing to ensure a material or product meets some predefined specification. A universal testing machine is used to measure the mechanical properties of materials intension, compression, bending or torsion. Common properties of interest include Offset Yield Strength, Young’s Modulus, Poisson's Ratio, Tensile and Compression Strength and Total Elongation.
