Small punch test metrics

Four basic metrics are obtained from a load-displacement curve of a material subjected to the small punch test. These include e initial stiffness, peak load, ultimate load, and the maximum displacement at failure. A fifth derived metric, integral work to failure (WTF), is found by integrating the area imder the... 

Characteristic features observed on load-displacement curves obtained using the shear punch apparatus. An initial and hardening stiffness in addition to the peak load are the primary metrics used to perform analytical comparisons. Like the conventional small punch test, the shear punch test also may be interpreted qualitatively. (Adapted from Kurtz et al. 2002.)...

Akagi et al. [21] used metrics from the small punch test to investigate the behavior of candidate crosslinked UHMWPE knee bearings. The authors tested the candidates... 

Representative load-displacement curve developed by testing of a small punch Sf>ecimen in equib-laxial tension curve here reflects typical behavior of GUR 1020. Primary metrics including initial stiffness, peak load, ultimate load, and ultimate displacement. WTF shown in grey. Unirradiated UHMWPE exhibits a bend and a stretch region as shown.
