14. ABSTRACT 

As the XM982 projectile transitions to its production phase, several questions were raised regarding the rounds’ response to 

tactical vibration in the Paladin vehicle. The U.S. Army Research Laboratory carried out an extensive program to characterize 

the straps used to retain the projectiles in the Paladin vehicle. The characterization tests included stiffness, short-term and 

long-term creep. A definite relationship is shown between a strap’s load carrying ability and time under stress as well as 

number of stress cycles.

Introduction 

As the XM982 projectile transitions to its production phase, several questions were raised 

regarding the rounds’ response to tactical vibration in the Palladin vehicle. As a result, the U.S. 

Army Research Laboratory began an extensive program to characterize the rounds’ response to a 

variety of strap configurations. One part of this characterization involved understanding strap 

materials themselves; this report details that investigation. 

Strap Material Characterization 

Three tests were performed for each of the five strap materials identified in table 1. Each test 

utilized a new, previously untested specimen and was conducted on an Instron load frame at 

quasi-static rates. Five materials were tested as identified in table 1. The typical test setup for a 

strap in the Instron machine is shown in figure 1.

Stiffness Test 

The objective of this test was to obtain the strap stiffness and then verify its repeatability. The 

straps were extended to 0.375 in. or loaded to 100 lbs (whichever occurred first) and then 

relaxed. This loading was repeated 20 times, resting 30 s between cycles. During the last cycle, 

the strap was pulled to 0.4 in. 

Data from a typical test is shown in figure 2. The blue curve is the repeated load cycling of the 

test and shows 20 excursions from 0 pounds force to 100 pounds force with the associated 

hysteresis. The red lines are sequential fitting of the force-deflection curve with a linear fit. This 

fit is biased towards providing a better approximation of the curve at its higher force levels. The 

fit represents an approximate stiffness of the strap and is a linear fit of the portion of the curve 

between 1⁄3 of the peak force and the peak force for the given load cycle. The green line provides 

an indication of the hysteresis of each loading cycle. It indicates the deformation distance 

between the loading cycle’s peak force and its relaxation to zero force.

The plots in figure 3 summarize the data from all of the tested straps in test 1. The first plot 

(figure 3A) shows how the stiffness varies for each strap with each subsequent pull. The second 

plot (figure 3B) shows how the relaxation distance varies between load cycles. The stiffness 

measured in figure 3A has not been normalized for strap length, so it is applicable only to that 

particular strap. Both graphs clearly indicate that the response of all the straps change with 

repeated load application. The stiffness plot indicates that after five load applications, the 

stiffness change is minimal.

Figure 3. Test 1 summary. 

Short Term Creep Test 

The second test for each strap was a short term creep response. Each strap was pulled to 0.3 in. 

displacement in 0.05 in. increments. Between each increment, the strap was permitted to relax 

for 2 min. After being loaded to the full 0.3 in., the strap was then unloaded and the same 

loading profile was repeated. 
4 

A distance of 0.3 in. was chosen based on the measured displacements of a strap in use. As 

shown in figure 4, the strap was pulled tight and the first fiducial line was marked. The strap 

was then released and a second fiducial was marked. Measuring across the different clamps, the 

distance between these two fiducials ranged from 0.125 in. to 0.375 in.. A distance of 0.3 in. 

stretches the straps just slightly more than the service displacement but should not result in any 

strap damage. 

Figure 4. Displacement limits. 

Figure 5 shows the data from this test series. Each plot has four curves on it. The two red curves 

show displacement versus force and the two blue curves show time versus force. The solid red 

and blue curves are the first loading cycle and the dashed red and blue curves are from the 

second loading cycle. 

All of the straps displayed similar trends. There was some amount of relaxation of each loading 

increment. The relaxation force tapered off in an exponential fashion. There was a significant 

difference between Cycle 1 and Cycle 2 in three of five of the straps. The difference between the 

peak forces for both of the BWI T-6 (1 in. wide, 0.063 in. to 0.083 in. thick) straps was less than 

5% whereas the same difference for the other three straps (1 in. to 1.75 in. wide, 0.033 to 0.053 

in. thick) was approximately 40% to 50%. The T-6 C-9 strap manifested little difference 

between loading cycles for all increments of loading. The tester noted a ping or pop at 

approximately 1150 lbs indicating extreme fiber/seam stress for the BWI T-6 C-10 strap and a 

similar noise at 1300 lbs for the BWI T-10 C-7 strap. 

In these tests, the second loading cycle appears to provide a stiffer response than the first loading 

cycle, which is consistent with the stiffness tests. An exception is the BWI T-10 C-7 strap for 

which the second loading cycle appears softer than the first. This could be a result of damage 

imparted to the strap during the first loading cycle as indicated by the noise mentioned above.

Long Term Creep Test 

The objective of this test was to determine how each strap responds over a long duration when 

stressed. Each strap was stretched to 0.3 in. and held for 60 min. Then the tension was released 

(Cycle 1) and the strap was immediately pulled to 0.3 in. again and released without holding 

(Cycle 2). The data from this test series is plotted in figure 6. 

The solid red and blue curves in figure 6 represent the data from the Cycle 1. The dashed red 

and blue curves represent the data from the Cycle 2. The blue curves show the data plotted as 

force versus time and the red curves show the data plotted as force versus displacement. In all 

cases the force reduction resulting from the creep assumes a characteristic logarithmic shape. 

Although relaxation occurs throughout the entire hour period, the majority occurs within the first 

3 to 5 min. In all cases, the Cycle 2 does not achieve the same force at the displacement limit of 

0.3 in.. 

The 12361478 strap appears to follow an unusual force-displacement curve on the Cycle 1 

loading. It does not follow the typical exponential curve that the other straps follow. This may 

be due to some looseness in the strap that is taken up part way through the loading. For all the 

other straps, there appears to be minimal stiffening from Cycle 1 to the Cycle 2.

Summary 

This series of tests was designed to provide a characterized response for a series of different 

straps used to restrain the XM982 projectile during tactical vibration in a Palladin vehicle. Three 

tests were run to characterize a different aspect of the expected response. Repeated load 

application tests, as well as short and long term creep tests, were executed. As expected, the 

force that each strap applied to the projectile varied as function of time and number of loading 

cycles. These tests indicate that careful attention must be paid to changing tension in the straps 

over the duration of a round’s time in the field and that with each tightening, the turnbuckle/hook 

will likely need adjustment.
