Engineers are actively trying to mimic hard biomaterials such as mollusk shells and beaks because of their resilience and damage tolerance, which are believed to stem from hierarchical arrangements in their design. Technological advances in fabrication methods make it possible to create architected structural metamaterials using materials whose design and dimensionality are similar to those fou...

It is the purpose of this paper to point out the problems associated with flexible pavements, to summarize the research that the Joint High­ way Research Project has done in this field, and to outline present endeavors. In so doing, it must be recognized, first of all that flexiblepavement research, or the general problem of flexible-pavement design, consists of two parts. One of these is the m...

This paper presents a mesh-based geometric modeling method to create tessellated models of general structures, which can be the design results of conformal truss structure design, thermal design, topology design, material design, compliant mechanism design and others. A general structure configuration design format is proposed to describe the structures. A universal structure generating system ...
