The Theory of Linear Viscoelasticity – D. R. Bland – Google Books
Due to the process dependent PRs, i. In addition, it explains procedures for model fitting to measured values of complex modulus or compliance. Additionally, even if non-instantaneous gradual loading functions are employed the resulting PRs are still load and load history dependent. The non-homogeneous material results and conclusions presented herein apply equally to homogeneous viscoelasticity and per se do not influence the results or conclusions of the analytical development regarding viscoelastic PRs.
Consequently, they represent specialized PR responses applicable and limited to those particular load and history combinations. Furthermore, there viscielasticity no theoretical fundamental hint as to what loading path is required to produce a unique universal viscoelastic PR definition necessary for formulating a PR based constitutive relation or an EVCP protocol.
The final chapter examines model fitting to measured values of complex modulus or compliance. Account Options Sign in.

Additionally and independently, the required double convolution integral construction of linear viscoelastic constitutive relations vizcoelasticity the inclusion of PRs is cumbersome analytically and computationally needlessly highly CPU intensive.

Three detailed individual sections present examples of stress-related problems. The correspondence principle for sinusoidal. The present review and analysis paper is intended as a theoretical mechanics complement covering mathematical and physical modeling of a single original elastic and of six time and process i.
The text begins with an introduction to the concepts of viscoelasticity. The Theoretical Mechanics Perspective. His other books include Wave Theory and Applications.
This Class PR can be the one used if linexr is desired to express constitutive relations in terms of PRs, subject to the caveat applying to all PR Classes regarding the CPU intensiveness in the time space due to triple product and double convolution integral constitutive relations.
The theory of linear viscoelasticity
The mathematical model of instantaneous initial loading paths, based on Heavi-side functions, is examined in detail and shown to lead to infinite velocities and accelerations. The implications and consequences of such models on material characterization are analyzed and summarized. Analytical formulations and experimental measurements also examine the physical impossibility of instantaneously achieving time independent loads or strains or their rates thus making certain PR definitions based on constant state variables, while mathematically valid, physically unrealistic and unachievable.
Summary of the results of Chapter 2. Succeeding chapters explore the foundations of three-dimensional linear viscoelasticity and stress analysis. Materials Sciences and ApplicationsVol.

Pergamon Press, New York. The text begins with an introduction Numerous examples and figures blad the text. The analysis associated with an additional Class VII viscoelastic PR establishes it as a universal representation which is loading path and strain independent while still remaining time dependent.
Bland Limited preview – In short, these PR analyses apply to all linear viscoelastic material characterization. Such non-uniqueness of viscoelastic PRs renders them unsuitable as universal material descriptors.
The Theory of Linear Viscoelasticity. Although the analyses contained herein are generalized to non-homogeneous linear viscoelastic materials, the main focus is on PR time and process dependence.
