There are to date very few experiments reporting the measurement of creep compliance or of creep curves with AFM, since most measurements in this field are performed with instrumented nanoindenters and experimental protocols for the acquisition of creep curves are usually not implemented in commercial microscopes.

Creep compliance mapping by atomic force microscopy
Polymer, 2014Abstract We present a method for mapping the spatial distribution of viscoelastic properties of heterogeneous samples using the atomic force microscope (AFM). By applying a force step load protocol to induce time dependent sample indentations we measured the local creep compliance of the sample.

Dilational creep compliance in Langmuir polymer films
Soft Matter, 2011Creep compliance is a simple rheological tool to study flow properties in soft matter. As a proof of concept we have studied the dilational flow of Langmuir films made of poly(vinylacetate), a model flexible polymer. The creep response has been probed at different stresses, pointing out the existence of compliance features.

Local calibration of creep compliance models of asphalt concrete
Construction and Building Materials, 2017Abstract Thermal cracking is one of the main asphalt concrete distresses. Asphalt pavements typically experience thermal cracking at an early stage of their service life. The Mechanistic-Empirical Pavement Design (MEPDG) software utilizes a thermal cracking model to predict low temperature performance (NCHRP, 2004).

Contact creep compliance of viscoelastic materials via nanoindentation
Journal of Materials Research, 2006The creep compliance of viscoelastic materials such as synthetic polymers is an established metric of the rate at which strain increases for a constant applied stress and can, in principle, be implemented at the nanoscale to compare quantitatively bulk or thin film polymers of different structures or processing histories. Here, we outline the evolution

Master Creep Compliance Curve for Random Viscoelastic Material Properties
2014The objective of this study is to apply the time-temperature superposition principle (TTSP) to the viscoelastic material functions that exhibit a large degree of variability to predict the long-term behavior of a vinyl ester polymer (Derakane 441–400). Short-term tensile creep experiments were conducted at three temperatures below the glass transition ...

Investigation of Asphalt Mixture Creep Compliance at Low Temperatures
Road Materials and Pavement Design, 2008ABSTRACT The creep compliance is one of the main material characteristics used to describe low temperature behavior of the asphalt mixtures. It also serves as a primary input to the current thermal cracking model in the US that is used to predict thermally induced cracking in asphalt pavements over their service life. The current standard method in the

Determination of Asphalt Binder Creep Compliance Using Depth-Sensing Indentation
Experimental Mechanics, 2011Asphalt binders are common construction materials, however due to time- and temperature- dependence, their mechanical properties are often difficult to characterize. Several standard tests methods exist to describe their complex behavior. This paper presents an exploratory feasibility study of a flat-tip indentation testing to analyze the linear ...
