Sustainable Infrastructure impacts our well-being and day-to-day lives. The
infrastructures we are building today will shape our lives tomorrow. The complex
and diverse nature of the impacts due to weather extremes on transportation and
civil infrastructures can be seen in our roadways, bridges, and buildings. Extreme
summer temperatures, droughts, flash floods, and rising numbers of freeze-thaw
cycles pose challenges for civil infrastructure and can endanger public safety. We
constantly hear how civil infrastructures need constant attention, preservation, and
upgrading. Such improvements and developments would obviously benefit from
ourdesired bookseries thatprovidesustainable engineering materials anddesigns.
The economic impact is huge and much research has been conducted worldwide.
The future holds many opportunities, not only for researchers in a given country,
but also for the worldwide field engineers who apply and implement these
technologies. We believe that no approach can succeed if it does not unite the
efforts of various engineering disciplines from all over the world under one
umbrellatoofferabeaconofmodernsolutionstotheglobalinfrastructure.Experts
from the various engineering disciplines around the globe will participate in this
series, including: Geotechnical, Geological, Geoscience, Petroleum, Structural,
Transportation, Bridge, Infrastructure, Energy, Architectural, Chemical and
Materials, and other related Engineering disciplines.

Characterization of the Mechanical Properties
of Sensitive Clay by Means of Indentation Tests

Abstract. Instrumented indentation tests were carried out on specimens of
undisturbed clay, using various indenters at a constant rate of penetration of
0.5 mm/min. These tests were performed with 20-mm in diameter conical
indenters with apical angles of 60o, 80o, 97o, and 144.3o, as well as with a
Vickers indenter of semi-apical angle of 68.7o. Such tests allowed the deter-
minationofboththeundrainedshearstrengthandthe deformationmodulusof
theclay.Theundrainedshearstrengthwasfoundbyassumingthatafullyplastic
stressfieldresultedfromindenterpenetrationandbyusingslip-linetheory.The
deformation modulus was computed by assuming that the clay behaved elasti-
cally during initial penetration. The theory proposed by Love (1939) and later
extended by Sneddon (1948, 1965) was used to obtain values of Young’s
modulus. The expanding cavity model or ECM proposed by Johnson (1970,
1985)wasalsoemployedfortheinterpretationoftestresultsobtainedwithboth
sharp andblunt indenters.
Oneofthemostsignificantfindingsofthepresentstudyisthatthestructureof
the undisturbed claysufferssevere andprogressive breakdownwith increasing
penetration during indentation, which results in a dramatic decrease of the
strength and deformation parameters of the clay. Comparison between the
undrainedshearstrengthdeducedfromthequasi-staticindentationtestsandthe
dynamicSwedishfall-conetests,alsoindicatesthatS obtainedfromthelatter
u
testsaremuchhigherthanthecorrespondingdataderivedfromtheindentation
tests.Itisbelievedthatthepossiblecauseoftheoverestimationoftheundrained
shear strength deduced from the Swedish fall-cone tests is related to the very
high strain rateexperienced bythe fallingcone.

1 Introduction
Different test methodsare available for the determination ofthe mechanical properties
of materials. The results of these methods are employed for the design of engineering
structures and as a basis for comparison and selection of materials. For instance,
uniaxial tension and compression tests are commonly used to determine mechanical
