压缩一试验样品直至其破裂，此时的压力就是压缩极限负荷。

Breaking Load
Load which causes fracture in a tensile, compression, flexure or torsion test. In tensile tests of textiles and yarns, breaking load also is called breaking strength. In tensile tests of thin sheet materials or materials in form of small diameter wire it is difficult to distinguish between breaking load and the maximum load developed, so the latter is considered the breaking load.

In this case, the sample is just deformed, not brocken, but you can still use 压缩极限负荷.
