Modulus of Elasticity Testing

Modulus of elasticity testing is an essential method for evaluating how resistant materials are to elastic deformation. When materials experience stress or force, they can deform, potentially leading to product defects, waste, and customer dissatisfaction.

Ensure your materials can withstand the pressures they will encounter throughout their lifecycle with precise modulus of elasticity testing.

Modulus of elasticity meaning

The modulus of elasticity measures a material’s stiffness. The calculation is made applying force to a material and dividing the stress applied by the resulting elastic strain.

Stiffer materials have a higher modulus of elasticity. For example, steel has a much higher modulus than flexible materials like rubber.

Types of modulus of elasticity testing

There are several different types of modulus of elasticity, the most common being: 

Young’s modulus: Evaluating Rigid Materials

Young’s modulus, also called tensile modulus or traction modulus, is used to measure a material’s ability to withstand tension or compression. It is essential for evaluating the elasticity of rigid materials used in construction and manufacturing.

Shear modulus: Determining Material Rigidity

Shear modulus testing, also sometimes known as modulus of rigidity testing, is a method of determining the elastic shear stiffness of a material. It uses the ratio of shear stress to the shear strain to measure elasticity. It is typically carried out via a static torsion test or by a dynamic test that tends to use a torsional pendulum. 

Bulk modulus: Measuring Response of Elasticity Test

Bulk modulus testing is a way of determining a material’s response to (uniform) hydrostatic pressure. This is very useful for testing building or construction materials that may be used in underwater settings, from sea stations to swimming pools.  

Materials suitable for modulus of elasticity testing 

Modulus of elasticity testing is suitable for determining the elasticity of a wide variety of materials and in commonly used in a variety of industries. A few of the materials most frequently tested include:

Modulus of Elasticity Testing Solutions

United Testing Systems, part of Industrial Physics, provides a comprehensive range of universal testing machines (UTMs) designed for modulus of elasticity testing.

These industry-leading instruments are also capable of performing tension (pull testing), compression, and bend/flex testing.

From our 2.5 kN (550 lbf) single-column system up to our 2,000 kN (450,000 lbf) servo-hydraulic system, Industrial Physics’ test frames are known for their quality, durability, and affordability.

Once, you’ve performed your test and viewed the results on our easy-to-read display screens or transferred them to a graph. You can see the modulus of elasticity plotted as the ratio of the stress in relation to the corresponding strain (displacement). Different types of elastic modulus can be measured, including Young’s modulus, shear modulus and bulk modulus.

Industrial Physics’ test systems, along with our DragonFly UTS software package and wide selection of grips and extensometers, give you a highly accurate tool for performing this critical material test procedure.
