Discover the materials testing techniques with Engineering terms
Standard engineering calculations are a set of fundamental mathematical equations and methods used routinely by engineers in various fields to solve common engineering problems. These calculations are essential in designing, analysing, and understanding engineering systems and structures. They often involve principles from physics, mechanics, thermodynamics, electrical theory, materials science, and other scientific disciplines
Standard engineering calculations are built into Exponent and Exponent Connectsoftware 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
Typical compression and tensile tests
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
If you can’t see these in your software then it might be that you need to update your software version. You can do this quickly, and free of charge (for existing users) via our Software Updates page.
