Mechanical properties of composite materials can be improved by tailoring their microstructures. The mesomechanics of materials considers teh effect of microstructures on the materials' properties, seeking to bridge the gap between micro-and macroscale models of materials. Mesomechanics represents an approach to assessing existing and improving new materials, based on the analysis of interrelations between macroscale properties of materials, microscale physical mechanisms of deformation and damage, and the interaction effects between many microstructural elements.
The book presents the concept and methods for the computational analysis of interrelationships between mechanical properties (e.g. strength, damage resistance, and stiffness) and microstructures of composite materials. The methods of mesomechanics of composites are reviewed and applied to the modeling of the mechanical behavior of different groups of composites. Individual chapters are devoted to the computational analysis of the microstructure-mechanical properties relationships of particle-reinforced composites, interpenetrating phase and unidirectional fiber reinforced composites, and machining tools materials.
The book is aimed at scientists and professionals working in the areas of the mechanics of materials and materials science as well at graduate and postgraduate students.
