TRANSLATIONAL RESEARCH IN MECHANICS AND MATERIALS WITH EMPHASES ON SUSTAINABILITY AND DURABILITY
Sustainability is defined as the development that meets the needs of the present without compromising the ability of future generations to meet their own needs according to the Brundtland Commission, 1983 in Our Common Futures. Sustainability includes all aspects of the society, such as building and civil infrastructural systems, energy, environment, health, safety, life-cycle analyses, etc. The Hakka rammed earth buildings (Tulou) are good examples of sustainability over the ages. There are many challenges and barriers for sustainability. In addition new technologies such as nanotechnology and smart materials play a key role in achieving sustainability. Durability and accelerated tests are essential for new materials. A promising process in new material design is using reinforcement via the placement of hard particles in a matrix. Here we present the modeling and prediction of the elastic response and damage propagation in composites reinforced by stochastically-dispersed particles. The microstructure of the composite, such as particle size, shape and distribution, plays an important role in mechanical behavior. Based on a microstructure finite element model, a simple theory is developed to predict the mechanical behavior of particlereinforced composite material. The internal detailed stress distribution and damage propagation in the composite can be obtained. This work presents a comprehensive understanding of the mechanics of composite material reinforced by stochasticallydispersed particles. Other research and challenges in mechanics and materials, including multi-scale/multiphysics modeling and nanomechanics are to be discussed.
