ABSTRACT

A survey of literature on the mechanical behavior of

polymers subject to dynamic loads in a wide temperature range

has been made. The data showing the variation of yield strength,

and elongation with strain rates and temperatures were tabu-

lated and plotted; the results obtained from tension and com-

pression modes of loading are graphed separately. A compre-

hensive reference section is provided.

It is observed that the behavior of polymers under dyna-

mic loading is different from static loading. The yield

strengths are generally higher under dynamic loading than the

static ones and they decrease with an increase of temperature.

INTRODUCTION

In the advent of recent advancement in plastic technology,

various polymeric materials are being introduced into indus-

trial and military use. Consequently, the precise knowledge

- 2 -

about their mechanical properties is highly desirable. The

purpose of this survey is to obtain the experimental data on

mechanical properties of polymers available in the literature,

including the effects of strain rate and temperature. The per-

tinent data are compiled, converted if necessary, and plotted.

This study is not intended as a critical review, but merely

serves as a source of information on the dynamic properties

of polymers.

The dynamic properties of polymers are highly dependent

on strain rate and temperature. They have been studied, pri-

marily in terms of the variance of yield strengths with strain

ri.te. The general behavior of polymers may be classified in

four distinct modes as shown in Pig. A and the yield strengths

for each mode are as follows:

a) Brittle Modes - Brittle failure sets in before yielding

(OF) - The yield stress is the failure load divided by

the initial cross-sectional area.

b) Brittle-Ductile Mode - The yield stress is taken as the

peak or maximum stress on the stress-strain curve. In

this mode, the failure follows shortly after yielding

CAP,).

c) Ductile Mode - There are two yielding levels (AP2).

The yield stress is taken as the maximum stress on the

stress-strain curve.

d) Homogeneous Mode - There is no typical yielding charac-

teristic (AF,,). This mode seems to occur at high tem-

peratures and in the region of glass transition

- 3 -

temperature for some materials (e.g., soe L-2)*. In

this case, the yield stress, B, is the stress obtained

at the intersection of a 2% strain line parallel to the

initial slope of the stress-strain curve (e.g., L-l).

,-F2

Engineering Strain

Figure A

In the tables of experimental results, the above four

definitions were used when the yield stress was taken from the

stress-strain curves. The method of measuring strain rate is

identified in the remarks column whenever it is available. It

should be noted that most of the tests conducted in this survey

were at temperatures between -50° and 150°F.

Letter and number in the parenthesis indicates the reference

number.

- 4 -

It is observed that in general, the yield strength, Gy ,

varies linearly with log £ , and that the slope of öy - log£

curve varies with the temperature. The interdependence of

strain rate and temperature is often expressed as a "shift

factor", a™. The factor a„ implies the horizontal shift of the

data points which represent the plot of yield strength versus

strain rate at a temperature corresponding to the data points

at reference temperature. The shift factor given by the

Williams, Landel and Ferry (WLF) equation* in its modified form

is:

f I0/.6+T-Ts (1)

where T denotes reference temperature and T is the glass

transition temperature (T = T + 50°C). Equation (1) is s g

applicable for the temperature range between T and T + 100 C. g g

Outside this region, the shift factor of glassy and highly cry-

stalline polymers is calculated from an equation of the Arrhenius

form:

ul *'* t«7 - i) <2)

# See, e.g., Perry, J.D., Viscoelastic Properties of Polymers,

John Wiley & Sons, Inc., New York, 1961.

where H is the activation energy for the particular transi-

tion of interest, R is universal gas constant, and TQ is the

temperature selected arbitrarily as reference. The Arrhenius

equation is not used in the glass transition region because

in this region, the activation energy is a strong function of

temperature. When the rigidity of the molecular backbone

reaches some limit, a new superposition procedure is needed

which involves» a vertical shift.

Using the shift factor, a™, the major portion of the curve

showing the relationship of the yield stress versus strain

rate times a temperature dependent constant may be repre-

sented by an equation of the form:

CY = K1 + K2 in((£/e,)aT) (3)

where Oy, £ , and aT are yield strength, strain rate and shift

factor, respectively, K, and K„ are constants which depend on

the type of material and on the reference temperature, a»■■* £.

is equal to 1 in/in/min.

RESULTS AND DISCUSSION

In this report, the test results obtained from tension,

compression, and torsion modes of loading are, in most cases,

plotted separately. The data are not only influenced by the

mode of loading, but also are affected by the type apparatus

used for the test. Properties may vary with specimen prepa-

ration such as heat treatment and the envirooient of testing

fev. \

- 6 -

such as humidity, etc. It should be noted that the treatment

of test results in the literature are generally not standardized.

It was also shown that different data were obtained by different

investigators for a similar test arrangement and material. This

is partly due to the high degree of sensitivity exhibited by

many plastics to the rate of strain and to their environmental

conditions.

The elongation in tension tests is reported as the per-

centage of elongation at break. The experimental data listed

in the tables, give both tension and compression as positive

values.

For most data collected, the strain rate is held constant

during the tests. However, when the strain rate is specified

by any other method, the information is provided in the tables.

If the strain rates are calculated from the cross-head speed,

then the approximate strain rate is obtained by dividing the

cross-head speed by the gage length. This approximation has

been used for a maximum engineering strain of 205? (C-2).

In general, the dynamic yielding strengths are higher than

the yielding strength under the static loads. They also de-

crease with an increase in temperature.

The List of Investigations summarizes the pertinent in-

formation obtained from the survey. Tables 1-9 provide the

dynamic properties for various polymers and Figures 1-10 show

the variation of ;yield strength vs. strain rate for a wide

temperature range. Literature whose data were not used in the

tabulation are listed in the Bibliography.

It is expected that this report be used as a source for

quantitative information for design purposes and future research.
