Similarity relation upon the puncture of a thin sheet
Puncture is a break in a membrane (clamped on a distant peripheral outline) caused by pressing an indenter whose diameter is much less than the diameter of the membrane. Based on the measurements of the force P required for puncturing an aluminum foil over a wide range of relationships between its t...

Summary: | Puncture is a break in a membrane (clamped on a distant peripheral outline) caused by pressing an indenter whose diameter is much less than the diameter of the membrane. Based on the measurements of the force

required for puncturing an aluminum foil over a wide range of relationships between its thickness
h
and the indenter radius
R
(for
h/R
= 0.12–7.00, i.e., from a blunt-indenter-thin-foil to a sharp-indenter-thick-foil case), we found a common nonlinear dependence of the dimensionless force
