Mechanical design of an experimental aspirated compressor
In this thesis, the design and construction of a low speed, aspirated fan stage is described. The design intent of this stage is to increase the work per blade row by control of the boundary layers within the flowpath. The low speed fan stage is designed to produce a pressure ratio of 1.5 at a tip …

Multiscale structural and mechanical design of mineralized biocomposites
… as to impede crack propagation. Gradient in the mechanical properties are ubiquitous at both the microscale (scales) and the nanoscale (nacre tablets), preventing stress concentration and enhancing strain distribution. The armored scales thus exhibit a unique spatial functional form of mechanical …
