Elongation at tear

Elongation at tear

Elongation at tear or elongation at break is the potential ratio of length change ΔL (at break) to the original length L0.

Whereby:

Elongation at tear = (length change / original length) x 100

εR = (∆L/L0)x100.

The elongation at tear expresses the capability of a material to follow shape changes without cracking.
