Sensitivity to material contrast in homogenization of random particle composites as micropolar continua

摘要

Several composite materials used in engineering - such as ceramic/metal matrix composites, concrete, masonry-like/geo materials and innovative meta materials - have internal micro-structures characterized by a random distribution of inclusions (particles) embedded in a matrix. Their structural response is highly influenced not only by the mechanical properties of components, but also by the shape, size and position of the inclusions.
