Failure Mode Identifications Of Rc Beams Externally Strengthened With
… the reinforced concrete beams and compare their failure modes. The main goal is to determine the CFRP design on the reinforced concrete beams that result in a progressive and gradual failure mode with enough warning before final failure. Different CFRP designs are investigated and compared with …

Characterization and Failure Mode Analysis of Cascode GaN HEMT
… GaN HEMT, an accurate behavior-level simulation model is developed in this thesis. The packaging related parasitic inductance, including both self-inductance and mutual-inductance, are extracted based on finite element analysis (FEA) methods. Then the accuracy of the simulation model is verified …

Failure Mode Effects Analysis of Auto-verification in the Clinical Laboratory
… the risks and benefits of auto-verification. Failure Mode Effect Analysis is used to describe and characterize the risks associated with common clinical laboratory practices. Prothombin Time (PT) is used to illustrate a variety of parameters to be considered before implementing …

The Development of a Manufacturing Failure Mode Avoidance Framework for Aerospace Manufacturing
… through the prevention of identified potential failure modes that is based on the principles of the existing Failure Mode Avoidance framework used for automotive system design. The tools and techniques that exist in the literature are reviewed in order to understand the best practice, and …

The identification and modelling of the dominant failure mode in hot forging tooling
The aim of the thesis is the identification and modelling of the dominant failure mode in hot forging tooling, used in the production of nickel based superalloy compressor blades. A preliminary study identified the most frequently occurring part defects that cause tool failure. The forming process …

Multi-Failure Mode Risk Assessment of the Houston/Galveston Bridge System to Hurricane Threats
… risk assessment of bridges for multiple failure modes: bridge deck uplift and bridge scour. Due to recent hurricane damage of bridges, emergency managers need to understand the potential state of the bridge network immediately following a storm for effective mitigation and post-event …

The application of failure mode and effect analysis to evaluate risks associated with outsourcing decisions
… gave the opportunity to develop a tool based on Failure Mode and Effect Analysis (FMEA). The typical FMEA was researched and analyzed for its ability to be an effective tool in outsourcing risk decisions. Small alterations on the typical FMEA were made to provide a relevant tool to analyze …

Gas lift valve failure mode analysis and the design of a thermally-actuated positive-locking safety valve
Gas-lifted oil wells are susceptible to failure through malfunction of gas lift valves. This is a growing concern as offshore wells are drilled thousands of meters below the ocean floor in extreme temperature and pressure conditions and repair and monitoring become more difficult. Gas lift valves …

Interaction of Variable Axial Load and Shear Effects in RC Bridges
… of strength, stiffness, energy absorption, and failure mode were found to be highly dependent on the axial loading pattern. High levels of constant or coincident compression resulted in increases in demands that were unmatched by any increases in capacity resulting in brittle shear-axial …

Uncovering and avoiding failure modes in driveline and tire/wheel NVH using a computational meta-model
… address this, the "Slider Bar" process and meta-model are presented. Based on the failure mode avoidance approach, the process and model allow the engineering teams to uncover and avoid potential tire/wheel and driveline NVH failure modes. Therefore, early in the product development process, …

Surface tracking in the inter-phase region of large transformers
… service lives and subject to various end-of-life failures. One failure mode occurs in the inter-phase region which leaves evidence of surface tracking along the barrier boards. The failure mode is thought to occur in three stages but the propagation mechanism is unclear. This project focuses on …

Failure Analysis and Casting a Gooseneck for Mashnee
… Herreshoff sailboat Mashnee recently failed. A failure analysis was conducted, and the failure mode identified. Steps were taken to mitigate this failure in a redesign of the gooseneck geometry, and the subsequent patternmaking, sandcasting, and finish machine was completed.

Strengthening Damaged Reinforced Concrete Beams and Slender Columns Using Ultra-High Modulus CFRP Plates
… plates, or a hybrid system, and then reloaded to failure. It was shown that the level of pre-existing damage has an insignificant effect on the strengthening effectiveness and the failure mode at ultimate. The 210 and 400 GPa CFRP of reinforcement ratio ρf = 0.17% increased the ultimate strength …
