The book summarizes recent international research and experimental
developments regarding fatigue crack growth investigations of
rubber materials. It shows the progress in fundamental as well as
advanced research of fracture investigation of rubber material
under fatigue loading conditions, especially from the experimental
point of view. However, some chapters will describe the progress in
numerical modeling and physical description of fracture mechanics
and cavitation phenomena in rubbers. Initiation and propagation of
cracks in rubber materials are dominant phenomena which determine
the lifetime of these soft rubber materials and, as a consequence,
the lifetime of the corresponding final rubber parts in various
fields of application. Recently, these phenomena became of great
scientific interest due to the development of new experimental
methods, concepts and models. Furthermore, crack phenomena have an
extraordinary impact on rubber wear and abrasion of automotive
tires; and understanding of crack initiation and growth in rubbers
will help to support the growthing number of activities and
worldwide efforts of reduction of tire wear losses and abrasion
based emissions.
This volume describes new insights into the main aspects of rubber
degradation by material's fatigue, wear and aging evolution, as
well as their impact on mechanical rubber properties. It provides a
thorough state-of-art explanation of the essential chemical,
physical and mechanical principles as well as practices of material
characterization for wear prediction, and to convey or define novel
strategies and procedures of planning effective wear test programs.
The initiating factors of abrasion, the development of surface
abrasion on sharp and blunt tracks (so called cutting and chipping)
and the influence of smear and lubricants is also summarized. The
volume is of interest to research scientists in related fields from
academia and industry.
Elastomers are found in many applications ranging from technology
to daily life applications for example in tires, drive systems,
sealings and print rollers. Dynamical operation conditions put
extremely high demands on the performance and stability of these
materials and their elastic and flow properties can be easily
adjusted by simple manipulations on their elastic and viscous
properties. However, the required service life suffers often from
material damage as a result of wear processes such as abrasion and
wear fatigue, mostly caused by crack formation and propagation.
This book covers interdisciplinary research between physics,
physical chemistry, material sciences and engineering of elastomers
within the range from nanometres to millimetres and connects these
aspects with the constitutive material properties. The different
chapters describe reliable lifetime and durability predictions
based on new fracture mechanical testing concepts and advanced
material-theoretical methods which are finally implemented in the
finite element method for structural simulations. The use of this
approach allows a realistic description of complex geometrical and
loading conditions which includes the peculiarities of the
mechanical behaviour of elastomeric materials in detail.
Furthermore, this approach demonstrates how multi-scale research
concepts provide an ambitious interdisciplinary challenge at the
interface between engineering and natural sciences. This book
covers the interests of academic researchers, graduate students and
professionals working in polymer science, rubber and tire
technology and in materials science at the interface of academic
and industrial research.
