How to measure Engineering Terms with your Texture Analyser

Standard engineering calculations have now been built into Exponent and Exponent Connect software for quick calculation of specific moduli, stresses, strains, strengths and energies which are particularly suited to materials testing applications for our range of Texture Analysers.

Each calculation is designed to be used with a very specific test setup (for example, cuboid three point bend testing) as the specific equations required for analysis depend on the sample and test geometry. A help page is supplied within the software for each quick calculation explaining the parameters that must be entered into the software by the user (such as film thickness) and a derivation and reasoning behind every equation used.


The quick calculation macros should be studied before they are used so the user is familiar with how each macro works, and edit the macro if further calculations need to be added or existing calculations tailored to the specific behaviour of the test sample.

Regardless of whether the test is performed in compression or tension, a resulting curve can be analysed to obtain the following typical parameters:

• Strain rate
• Young’s Modulus
• Tangent, chord and secant modulus
• Resilience
• Yield stress
• Strain to yield
• x% proof stress
• Maximum stress
• Strain at maximum stress
• Energy to maximum stress
• Breaking strain
• Hysteresis 
• Energy to failure

When specifically measuring in tension additional parameters may include:

• Necking onset
• Ultimate tensile strength 
• Strain hardening parameter 
• Strength coefficient

Flexure using three point bend for cuboid and cylindrical samples:

• Yield stress 
• Young’s Modulus 
• Flexural strength 
• Toughness

Indentation using conical and spherical probes:

• Indentation modulus 
• Hardness 
• Elastic energy 
• Plastic energy 
• Indentation energy

Puncture of uniform thickness thin films using spherical probes:

• Stiffness 
• Strength 
• Toughness 
• Failure Strain
