STRUCTURAL HEALTH MONITORING OF FIBER REINFORCED COMPOSITE STRUCTURES UNDER HIGH VELOCITY IMPACT LOADS

Description
This thesis encompasses research performed in the focus area of structural health monitoring. More specifically, this research focuses on high velocity impact testing of carbon fiber reinforced structures, especially plates, and evaluating the damage post-impact. To this end, various non-destructive evaluation techniques such as ultrasonic C-scan testing and flash thermography…

This thesis encompasses research performed in the focus area of structural health monitoring. More specifically, this research focuses on high velocity impact testing of carbon fiber reinforced structures, especially plates, and evaluating the damage post-impact. To this end, various non-destructive evaluation techniques such as ultrasonic C-scan testing and flash thermography were utilized for post-impact analysis. MATLAB algorithms were written and refined for the localization and quantification of damage in plates using data from sensors such as piezoelectric and fiber Bragg gratings sensors. Throughout the thesis, the general plate theory and laminate plate theory, the operations and optimization of the gas gun, and the theory used for the damage localization algorithms will be discussed. Additional quantifiable results are to come in future semesters of experimentation, but this thesis outlines the framework upon which all the research will continue to advance.

Eyewitness identification has been one of the most crucial components in identifying perpetrators in criminal cases. Misidentification of a suspect often has detrimental effects, with many innocent individuals being wrongfully convicted. In order to fully understand the causes of misidentification, a proper understanding of the process of eyewitness identification must be understood in order to ensure that fewer individuals are falsely imprisoned.
