static puncture force

According to Langenscheidt Technik, Stempeldurchdrückversuch is static puncture test (for geotextiles).

"uses a pyramid shaped piston which is pushed slowly with a cyclic up and down motion (dynamic test) as well as at rest (static test) trough the geotextile.The deformation and the puncture force are continuously measured. The determined maximum force is the static puncture force respectively the dynamic puncture force both of them being a mean of assessment in the RVS 8S.01.2 standard

Für eine Beurteilung des Durchdrückverhaltens von Geotextilien sind im deutschsprachigen Raum vorwiegend der Stempeldurchdrückversuch, mit dem die Kraftaufnahme bei statischer Belastung simuliert wird sowie der Kegelfallversuch, mit dem ein Schüttvorgang nachgestellt wird, von Bedeutung.

The puncturing-resistance of geotextiles is commonly judged on basis of the results of the CBR-puncture test, which allows the simulation of a static load and the cone drop test, which gives the opportunity to imitate a dynamic load.

neutral  Deborah Shannon: Stempel- suggests to me the alternative, the dynamic force. This document www.gb.bv.tum.de/fachsektion/veroeffentlichungen/ wilmers.pdf mentions 'plunger puncture force', as another alternative

  -> I've never been good at physics. Maybe just puncture force to be on the safe side?
