Rational design methodology for fire exposed load bearing structures

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Toward a Methodology of Rational System Design

In this paper I defend the view that there are rational methodological criteria for preferring one system design1 over another and that they are substantially the same as those of the scientific method. The parallels between the notion of a rational system design and the notion of a rational scientific theory are not coincidental: they reflect a fundamental similarity between the invention of d...

Rational design of self-assembly pathways for complex multicomponent structures.

The field of complex self-assembly is moving toward the design of multiparticle structures consisting of thousands of distinct building blocks. To exploit the potential benefits of structures with such "addressable complexity," we need to understand the factors that optimize the yield and the kinetics of self-assembly. Here we use a simple theoretical method to explain the key features responsi...

Design and fabrication of CoCrMo alloy based novel structures for load bearing implants using laser engineered net shaping

Developing Process Design Methodology for Investment Cast Thin-Walled Structures

Components for engineering systems, such as gas turbines and jet engines operating at high temperature are usually produced in superalloys. The investment casting process is most widely used for manufacturing these components due to the ability of the process to produce parts with complex geometries to close dimensional tolerances. Other processing routes are less advantageous due to high mecha...
