Book Description

The book explores the state of the art in the mechanics of fibrous media, providing an overview of the theoretical, modelling and practical aspects of designing and working with these materials. It also describes the advanced methods needed to handle their specific features, including the mechanics of generalized continua, dedicated homogenization methods and computational techniques, and presents applications of fibrous media to diverse fields and over a broad spectrum of scales, ranging from aeronautics to biomechanics.




Mechanics of Fibrous Networks


Book Description

Mechanics of Fibrous Networks covers everything there is to know about the mechanics of fibrous networks, from basic analysis of simple networks to the characterization of complex cases of deformation, loading, damage and fracture. Looking at various types of fibrous materials, the book studies their microstructural characterization, quantification of their mechanical properties, and performance at fiber and network levels. In addition, the book outlines numerical strategies for simulation, design and optimization of fibrous products. Techniques for testing the mechanical response of these materials in different loading and environmental conditions are outlined as well. This comprehensive resource will aid readers in obtaining qualitative data for various fibrous networks. In addition, it will help them develop modeling strategies and fine-tune mechanical performance fibrous networks and products by changing their microstructure to develop new products with desired properties and performance. Discusses all the main features and characteristics of fibrous networks, including their microstructural characterization, quantification of their mechanical properties, and performance at the fiber and network level Covers both basic analysis of simple networks as well as complex cases of deformation, loading, damage and fracture of fibrous networks Outlines advanced numerical schemes for simulation, design and optimization of various fibrous materials










Nonlinear Mechanics of Soft Fibrous Materials


Book Description

The book presents a state-of-the-art overview of the fundamental theories, established models and ongoing research related to the modeling of these materials. Two approaches are conventionally used to develop constitutive relations for highly deformable fibrous materials. According to the phenomenological approach, a strain energy density function can be defined in terms of strain invariants. The other approach is based on kinetic theories, which treats a fibrous material as a randomly oriented inter-tangled network of long molecular chains bridged by permanent and temporary junctions. At the micro-level, these are associated with chemical crosslinks and active entanglements, respectively. The papers include carefully crafted overviews of the fundamental formulation of the three-dimensional theory from several points of view, and address their equivalences and differences. Also included are solutions to boundary-value problems which are amenable to experimental verification. A further aspect is the elasticity of filaments, stability of equilibrium and thermodynamics of the molecular network theory.

Mechanics of Random-fiber Networks


Book Description

The mechanical interactions between fibers in a dense random-fiber network transmit stress, cause fiber curvature, and influence fiber orientation in the processing of many types of composites. A few theories describe the mechanics of fiber networks, but almost no simulation results are available. Here, we report a direct numerical simulation of the mechanical behavior of random-fiber networks.




Cellulosic Materials


Book Description

The objectives of this book are twofold : To provide a thorough examination of the materials science of cellulosic fibers with emphasis on the characterization of structure-property relations, and To advance knowledge of how to best analyze cellulosic fibrous networks and composites, and, ultimately, engineer 'novel' cellulose-based systems of superior performance and functionality. The book is structured in five chapters which provide a sequential treatment of the running theme : deformation mechanics and the physical, morphological and mechanical characterization of native cellulose fibers networks and composites.
