Compression testing is a very common testing method.  It may be used to measure the compressibility of a material as well as the recovery of a material that has been compressed to a load and held over a time period.  Compressive tests are used to determine the material behaviour under load.  The maximum stress a material can sustain over a period of time under load (constant or progressive) is determined.  

Compression testing is often done to a break or to a limit.  When the test is performed to a break (rupture), a break detector is used.  When the test is performed to a limit, either a load limit or deflection limit is used.

Common results available from Lloyd Instruments™ materials testing systems for compression testing are:

• Load at Rupture
• Deflection at Rupture
• Work at Rupture
• Maximum Load
• Deflection at Maximum Load
• Work at Maximum Load
• Stiffness
• Chord Slope
• Offset Yield
• Stress
• Strain

Compression testing can be carried out on a range of Lloyd Instruments materials testing machines together with NEXYGENPlus data analysis software when more comprehensive testing results are required.

Common standards for determining Compressive Strength

• ASTM C773
• ASTM D575
• ASTM D623
• ASTM D695
• ASTM D395
• ASTM E9
• ASTM E209
• ASTM F36
