COMPRESSION TESTING
|
|
|
In theory, the compression test is simply the opposite of the tension test with
respect to the direction of loading. In compression testing the sample is squeezed
while the load and the displacement are recorded. Compression tests result
in mechanical properties that include the compressive yield stress, compressive
ultimate stress, and compressive modulus of elasticity. Compression specimens must
be short compared to their diameter so that column effect will not cause bending
with eccentric, unequal loading.
