An architecture for a function driven mechanical design solution library

Creator:

Wood, Stephen L.

Abstract:

The engineering design process and the advancement of future computer-aided-design systems need new design aids to be used during the conceptual design phase. This design phase is where information gathering and understanding of the problem are developed, analyzed and broken into small more manageable elements. These elements consist of customer...

Kinematic analysis of legged system locomotion on smooth horizontal surfaces

Creator:

Baek, Yoon Su

Abstract:

This thesis presents a model of legged locomotion in which position and velocity of body are directly controlled by positions and velocities of feet. One central relationship between foot acceleration, leg stroke and body velocity is developed. Procedures for determining all parameters of a step sequence including periods of constant...

Kinematics of arthropod legs : modeling and measurement

Creator:

Albright, Stephen L.

Abstract:

This thesis presents a method for determining the kinematic geometry of arthropod legs. A kinematic description makes possible the analysis of arthropod leg motion, as a prelude to investigating how various arthropod species are able to negotiate diverse terrains. Such knowledge will aid in design of legged vehicles. The focus...

Three-dimensional, nonlinear viscoelastic analysis of laminated composites : a finite element approach

Creator:

Wang, Min

Abstract:

Polymeric composites exhibit time-dependent behavior, which raises a concern about their long term durability and leads to a viscoelastic study of these materials. Linear viscoelastic analysis has been found to be inadequate because many polymers exhibit nonlinear viscoelastic behavior. Classical laminate theory is commonly used in the study of laminated...

Rebound predictions of mechanical collisions

Creator:

Lai, Liang-Ju

Abstract:

Predictions of mechanical collisions between two bodies frequently cannot be completed by the impulse-momentum equation together with a complete description of the motion of the system at the initial contact. Additional account must be taken of the deformations and frictional interaction induced by the impulsive reaction force, where the bodies...

Ductile fracture of metals under triaxial states of stress

Creator:

Schrems, Karol Krumrey

Abstract:

Silver interlayers between maraging steel base metal were examined to evaluate mechanisms leading to ductile failure in constrained thin metals. The constraint of the maraging steel base metal during uniaxial testing of constrained thin silver results in a large hydrostatic tension component, a small von Mises effective stress, and negligible...

Drilling process evaluation by predicting drilled hole quality and drill bit wear with on-line acoustic emission signals

Creator:

Wang, Kuang-Jen, 1962-

Abstract:

Improvement of manufacturing productivity is dependent on the successful automation of manufacturing processes, the success of which is based in turn upon the availability of information which describes the state of manufacturing operations. Acoustic Emission (AE) signals related to the cutting process and tool wear have been recently applied to...

A study of ignition and propagation of combustive synthesis reaction between titanium and carbon

Creator:

Hernandez-Guerrero, Abel

Abstract:

Combustive Synthesis or Self-Propagating High-Temperature Synthesis (SHS), is an energy-efficient combustion method of producing metallic, ceramic and composite materials from their constituent powders. This thesis presents the results of an experimental and numerical evaluation of the propagation velocity for the SHS solid-solid reaction of titanium and carbon, as well as...

An experimental study of friction factors and mixed convection in the thermal entrance region of vertically narrow, horizontal rectangular channels for different heating conditions and aspect ratios

Creator:

Hong, Seung-Ho

Abstract:

Heat transfer and fluid mechanical behavior of water flowing horizontally in vertically-narrow rectangular channels was studied in this work. Friction factor and Nusselt number variations were determined experimentally for four different wall heating conditions, and for aspect ratios(height to width) of 5, 4, 3, 2, and 1. Wall heating conditions...
