CURE DEPENDENT CREEP COMPLIANCE OF AN EPOXY RESIN

1999
The cure dependent creep compliance of a difunctional epoxide/tetrafunctional amine epoxy is investigated. Creep data at several cure states is taken over a range of temperatures and shifted according to time-temperature superposition to obtain master curves. The dependence of creep behavior on cure state is shown to be quite dramatic.

Analysis of creep compliance curves of food gels

1988
The rheological properties of some simple food gels from fababean protein, gelatine and agar-agar have been studied as a function of concentration. Rheological parameters were derived from the creep compliance curve. The gels could be explained according to the six element Burger model.

Calculation of discrete relaxation modulus and creep compliance

Rheologica Acta, 1999
Muntz theorems from classical approximation theory are used to lay the mathematical foundations for discrete spectral representations of the relaxation modulus and creep conpliance. Algorithms that can automatically generate nonnegative discrete relaxation and retardation strengths are formulated by using the nonnegative least square method.

Relations Between Relaxation Modulus and Creep Compliance in Anisotropic Linear Viscoelasticity

Journal of Elasticity, 2007
The results obtained previously for scalar and class \(P\) completely monotone relaxation moduli are extended to arbitrary anisotropy. It is shown for general anisotropic viscoelastic media that, if the relaxation modulus is a locally integrable completely monotone function, then the creep compliance is a Bernstein function and conversely.

Determination of Dynamic Storage and Loss Compliances from Creep Data

Journal of Rheology, 1979
A pair of empirical equations are proposed for the purpose of approximating the dynamic mechanical viscoelasticity functions, the storage compliance, J′(ω), and the nonviscous loss compliance, J″(ω)−1/ωη, from the value of the recoverable compliance, Jr(t), and its logarithmic slope, m(t)=d log Jr(t)/d log t.

Three-Dimensional Microstructural-Based Discrete Element Viscoelastic Modeling of Creep Compliance Tests for Asphalt Mixtures

, 2011
Microstructural-based discrete element (DE) models have been used for a better understanding of asphalt pavement concrete since the late 1990s. Most current studies have been done with two-dimensional (2D) models.

Interconversion between Relaxation Modulus and Creep Compliance for Viscoelastic Solids

Journal of Materials in Civil Engineering, 1999
Methods of interconversion between relaxation modulus and creep compliance for linear viscoelastic materials are discussed and illustrated using data from asphalt concrete. Existing methods of approximate interconversion are reviewed and compared for their approximating schemes. A new approximate interconversion scheme that uses the local log-log slope

Shear creep compliance of polyoxymethylene copolymers with different molecular weights

AIP Conference Proceedings, 2014
Polyoxymethylene copolymer (POM) is considered a high performance engineering polymer with many applications due to its good chemical resistance and very good mechanical properties. It is known that mechanical properties of polymers are greatly influenced by their average molecular weight (Mw).

Compliance, relaxation and creep recovery of normal strength concrete.

2009
Calculating the long term serviceability of reinforced concrete structures requires an appropriate description of the mechanical properties of concrete. Among the long duration properties of concrete are shrinkage and creep of concrete. At relative humidities less than 96--99% concrete shrinks.
