As a highly skilled mechanical engineer, I have a deep understanding of the major issue of delamination in composite materials, especially under fatigue loading. My expertise in modeling this phenomenon and developing experimental databases enables me to predict and mitigate the effects of delamination. During my internship, I successfully developed crack propagation curves for 3D composite materials under Mode I, Mode II, and mixed mode (I+II) loading. I also conducted a thorough study and… Show more As a highly skilled mechanical engineer, I have a deep understanding of the major issue of delamination in composite materials, especially under fatigue loading. My expertise in modeling this phenomenon and developing experimental databases enables me to predict and mitigate the effects of delamination. During my internship, I successfully developed crack propagation curves for 3D composite materials under Mode I, Mode II, and mixed mode (I+II) loading. I also conducted a thorough study and analysis of the physical phenomena involved in crack propagation, including the use of acoustic emission signals to track and predict the advancement of the crack. With a proven track record of synthesizing experimental plans, writing progress reports, working in teams, negotiating with gauge suppliers, and utilizing NDT techniques, I am a valuable asset to any organization seeking a skilled mechanical engineer.

The objective is to establish an experimental procedure for measuring crack propagation energy under fatigue conditions, as a function of crack growth rate. This project will involve the use of various instrumentation methods such as CIN, EA, and crack gauges. Through this project, I have developed strong skills in mechanical testing planning, progress report writing, experimental data analysis, and the development of semi-empirical laws. As a result, I am well-equipped to make valuable… Show more The objective is to establish an experimental procedure for measuring crack propagation energy under fatigue conditions, as a function of crack growth rate.
