In current prosthetic practices, the design process heavily relies on the prosthetist’s expertise and the limited methods to quantify design choices. This thesis investigates the lower-limb prosthetic fitting process and the importance of the socket design. Previous research has taken local stiffness of the limb to provide prosthetists with more...
As CAD tools become more sophisticated, engineers are able to more easily create complex part geometries with minimal mass given strength and stiffness requirements. However, these complex part geometries can be difficult to subtractively manufacture, which consequently increases manufacturing cost and production time. This thesis presents a method independent of...
The intent of this research is to explore the entire design space of mechanism topologies by using a graph grammar synthesis approach. A new graph representation of planer mechanism has been developed to represent the planar mechanism with revolute (R), prismatic (P), and pin-in-slot (RP) joints. Following Gruebler's equation, the...
Creating effective packaging is about finding a balance between product protection during shipping and time consumption in the design process. Given time and cost constraints, it is hard to produce sufficiently protective padding while having it not be thicker than it needs to be. This thesis describes a method to...
In this work, metal-organic frameworks (MOFs) are computationally represented, generated, and evaluated. The organic linker molecules are represented as graphs and use graph grammars where the atoms are represented by nodes and the bonds are represented by arcs. The grammar rules that dictate the graph generation process work on the...
Recent advancements in joining operations and additive manufacturing now allow complex metal parts to be built up from raw materials, as opposed to being machined down from solid blocks. This not only opens up the design space, but also allows for much more efficient manufacturing. By decomposing a complex part...
Traditional electronic systems are usually fabricated via printed circuit boards (PCBs). In a regular PCB, the electronic components are placed and mounted on a two-dimensional board. Such a component layout limits the freedom in the component placement process which results in larger electronic devices. With the use of Additive Manufacturing...

Assembly planning is a crucial task for every manufacturing product. In general, assembly operations consume more than 30% of the total manufacturing time and cost. Therefore, any effort in optimizing assembly will have a significant impact on the economic success of manufacturing. Finding an optimal assembly plan by hand is...
Poor material utilization is inherent to conventional manufacturing processes, leading to high material waste and machining times. Additive manufacturing processes attempt to solve this issue by allowing production of near-net shapes, but the processes may be too expensive or infeasible. By leveraging both processes in a single part, the waste...
