This paper describes an algorithm based on accessibility-driven partitioning approach to automate the design of sacrificial multi-piece molds. Sacrificial multi-piece molds are used for producing geometrically complex gelcast ceramic parts. The algorithm presented in this paper analyzes the accessibility of the gross mold shape and partitions it using accessibility information. Each partitionin...

In the present work, ternary composites were synthesized from commercial titanias (Evonik Aeroxide P25, Aldrich anatase—AA and rutile—AR) two noble metals (gold platinum). This research focuses on composition of photocatalysts, especially metals. The ratio between varies 0.25 to 0.75% in each composite for metal. Transmission electron microscopy (TEM), X-ray diffraction (XRD) diffuse reflectanc...

Sacrificial wall systems consisting of lightweight concrete blocks have several advantages including versatility and high installation speed, making them effective tools for reducing the destructive effects blast waves. Particularly, in confined structures, they can be placed along path potential explosion waves such that internal failure mechanisms cause wave energy to dissipated. Numerous fac...
