This thesis presents the work conducted under the auspices of the Brite EuRam funded project, "PROGEAR" (contract number BRPR-CT98-0703), which sought to better understand the failure modes of injection moulded plastic gears, such that their performance and reliability could be improved. In so doing, the work built upon previous research conducted at the Power Transmission Laboratory, at the University of Birmingham. This research utilised a range of materials including plain polymers and polymer composites, as well a wide variety of gear geometries. In addition, the type of testing that was c

Abstract:

An analytical procedure, which retains the influence of finite deflections, is developed herein for the dynamic behaviour of rectangular shaped rigid-plastic beams. In the general formulation of the problem deformation is assumed to proceed under two distinct mechanisms depending on the extent to which the value of the peak pressure exceeds the static collapse pressure of the beam. These mechanisms are described by kinernatically admissible velocity fields that satisfy the appropriate continuity conditions. The governing equations of motion are derived from a variational statement consisting

For complex loading conditions the model is extended using multisurface plasticity.

Abstract:

Identification of regions containing plastic strain arising from the welding process is performed through the application of thermoelastic stress analysis (TSA) and finite element (FE) modelling. An approach is developed that removes the requirement to have a physical reference specimen for the component studied by developing a 'synthetic reference bitmap' using finite element analysis. The regions containing plastic strain can be identified with TSA by collecting data from a 'reference' plastic strain free specimen from the TSA data and creating a resultant bitmap. Here, a synthetic bitmap is

Based on historical and musicological texts and acts from the nineteenth to twenty-first century, this thesis proposes the concept of plastic resistance as an epistemological method to analyse the psychical and political perceptions of Beethoven’s life and music. Relying on the philosophy of Fichte and Lacan, I contend that the psychopolitics of this reception/resistance history is predicated critically on the musicians’ and listeners’ ability and affect to posit musical semantics unconsciously. I further argue that, during the negotiation of mastery, autonomy and subjectivity, the musical act

Abstract:

For automotive plastic parts there is a clear demand on an increased quality of the FE models. This demand is related to the increased use of simulations, both due to a reduced number of prototypes and an increased number of load cases. There have been studies showing a change of dynamic properties in injection molded components. The conclusion from these studies are that the change depends on residual stresses built in during the injection process. This study use simple models to try to get a working method and from the results find out the basic relations between residual stresses and dynami

Abstract:

The large ductile deformation response of stiffened plates subjected to blast loads is investigated and simplified methods of analysis of such response are developed. Simplification is derived from modelling stiffened plates as singly symmetric beams or as grillages thereof. These beams are further assumed to behave in a rigid, perfectly plastic manner and to have piecewise linear bending moment-axial force capacity interaction relations, otherwise known as yield curves. A blast loaded, one-way stiffened plate is modelled as a singly symmetric beam comprised of one stiffener and its tributa

The patterns and geometries were chosen to study the effect of needle spacing and array design on penetration force.

Abstract:

Semi-hot or warm forging is an economical alternative to the conventional forging processes by combining advantages of hot and cold forging processes. In this study, a new forging process sequence and design of the preform die for a part which has been produced by hot forging are proposed to be produced by semi-hot forging. Thermo-mechanical finite element analyses are performed over the stages of forging process. The billet and the dies are modeled as elastic-plastic bodies. Effects of preform die geometry on the die stresses and the forging load are investigated using finite element method.

Meanwhile, the metal became softer because of high temperature and was sheared by tangential force. Some debris was thus formed with shinning sparks and its components were almost metal, but not oxide. This mechanism is quite different from oxidational wear and is now termed as extrusion wear.

Abstract:

This study presents the applications of plastic limit analysis to offshore foundations and anchors, including the drag embedment anchors (DEAs) for mobile offshore drilling units (MODU’s) and spudcan foundations for jack-up platforms. In deep waters, drag embedment anchors are an attractive option for mooring of semisubmersible platforms due to low installation cost and high holding capacity; on the other hand, jack-up platforms are more stable than semisubmersible platforms but only can be placed in shallow waters. The analyses of anchor capacities are developed for an idealized anchor compri

Abstract:

Color is a visual characteristic which imparts the ability to categorize different objects. When light strikes an object, there are three possibilities as to what can happen. The light may be reflected, refracted or scattered. Human perception of color is due to a combination of these. Plastics are polymeric materials. Polymers are generally colorless and need colorants in order to have some color. One or more pigments in certain ratios can be used to give a specific color to plastics. Slight variations in the proportions of either of the used pigments, or their dispersion, may result in a col

碩士<br>國立臺北科技大學<br>製造科技研究所<br>98<br>Using CAE mold flow analysis software to simulate the plastic injection molding process can optimize the runner and gate design of the mold, reduce the test molding times, shorten the mold design hour through, and cost down of the mold making. In this study, Autodesk Mold Flow software will be used to simulate and analyze the total warpage of photo-frame above cover during injection molding. The gate number designed including single gate and double gate in the mold. Three types of plastic materials were used including ABS, ABS+PC, and PC. Finally, total warpa

This thesis uses a nonlinear finite element method to study the stress distribution of the thread under different fillet radius, depth, structu- re and plastic deformation. The analysis showed that the depth is not changed, increase the root fillet radius can reduce stress concentration of the thread root. In depth change, increase fillet radius will also make the thread root stress decrease, but when the fillet is too large, lead to roots become sharp, it will make the thread root s
