Obtaining Creep Compliance Parameters Accurately from Static or Cyclic Creep Tests
Journal of ASTM International, 2005Obtaining creep compliance parameters that accurately represent the creep response of asphalt mixtures is critical for proper evaluation of the thermal cracking performance, as well as load induced cracking performance of asphalt pavements. A power law, which uses three parameters to describe the creep compliance curve, is commonly used for asphalt ...

Nano-scale Creep Compliance of Hybrid Aerogels
MRS Proceedings, 2011ABSTRACTThe copolymerization between TEOS (tetraethoxysilane) and silane derivatives was promoted by the application of high power ultrasound to the precursor liquid mixtures in the same way as in the classical sol-gel method. The specific organic precursor was selected from the silanol-terminated polymer family with different molecular functionality ...

Creep compliance behaviour of direct compression excipients
Powder Technology, 1989Abstract Creep compliance was studied during tablet compaction by treating powder deformation or flow as analogous to the rheological behaviour of semi-solids. The creep curves could be differentiated into three distinct regions, corresponding to different types of rheological behaviour: elastic, visco-elastic and plastic deformation.

A model to predict creep compliance of asphalt mixtures containing recycled materials
Construction and Building Materials, 2018Thermal cracking is one of the major distresses in flexible pavements, especially in the northern part of the U.S. and Canada. With the increasing use of recycled materials like reclaimed asphalt pavement (RAP) and recycled asphalt shingle (RAS), asphalt

Analytical Compliance model for Flexure Hinge Considering Creep
2020 5th International Conference on Mechanical, Control and Computer Engineering (ICMCCE), 2020This paper deals with a study to determine a compliance model of flexure hinge considering creep subjected to pure applied moment. The work can be considered an extension of previous investigations on typical notched flexure hinge. Analytical equations are derived using Castigliano's second theorem and creep power-law that the creep constitutive ...

Creep compliance studies of egg yolk lipoprotein interfacial films
Biorheology, 1976Studies of creep compliance behavior of aqueous solutions of egg yolk lipoproteins indicate formation of viscoelastic films at n-heptane and n-hexane interfaces. Rheological parameters are reported. At other interfaces: water–air, water–cyclohexane, water–paraffin oil—the films were purely viscous.

Creep compliance response of a cohesive soil
Journal of the Franklin Institute, 1965Abstract The creep response of a cohesive soil tested in uniaxial compression is presented in terms of a creep compliance function. The variables considered include strain, time, stress level, and moisture content. The soil response is definitely nonlinear, but the stress dependence of the creep compliance is written in explicit form.

Evaluation of creep compliances of unidirectional fibre-reinforced composites
Composites Science and Technology, 1994Abstract In this paper, a method is proposed for the determination of the viscoelastic behaviour of unidirectional fibre-reinforced composites. The method is based on the model of Laws and McLaughlin. The interface problem is taken into account by using anisotropic elastic coefficients for the fibre. The non-linearity of the matrix is also considered

Measurement of Creep Compliance of Solid Polymers by Nanoindentation
Mechanics of Time-Dependent Materials, 2003Methods to measure the local surface creep compliance of time-dependent materials are proposedand validated in the regime of linear viscoelasticity using nanoindentation. Two different bulkpolymers, Polymethyl Methacrylate (PMMA) and Polycarbonate (PC), were employed in thevalidation study; though it is expected that the methods developed herein can be

Journal of the Korea Concrete Institute, 2005
In order to accurately assess the stresses occurring in the early-age concrete, a compliance function which can consider the characteristics of early-age concrete is required. Existing compliance functions, however, have the limit that they have been deduced from the data of hardened concrete and therefore, do not take into account the fast development
