Development and Calibration of a Frangible Leg Instrumented for Compression and Bending

Abstract

In order to quantify the loads transferred to a human leg during a landmine explosion, the lower portion of the Frangible Surrogate Leg (FSL) was modified to incorporate a load sensor. This report describes these modifications and the work carried out to calibrate the response of the modified FSL (FSLM) to static and dynamic loads. Non-destructive drop tests were performed to characterise repeatability from test to test for a given specimen, as well as the variation of response between specimens. Upon completion of these calibrations, five FSLM specimens were subjected to the explosion of 50-gram PE4 charges buried in sand. The standoff between the specimens and the soil surface ranged from 50 mm to 200 mm. The results demontrated how variations of the explosive input affects the load transmitted to the specimens and the resulting level of damage.
