BIOSKETCH: “Irfan Habeeb graduated from Indian Institute of Technology Madras with Bachelors and Masters in Aerospace Engineering in 2015. His research interests include mechanics of materials, composites, stochastic process and image processing. He is enthusiastic about hands-on activities from origami to radio controlled aircrafts. In addition to academia Irfan enjoys travelling, philosophy, standup comedies and futile arguments with friends. Currently he is pursuing PhD at Technion – Israel Institute of Technology in the department of Mechanical Engineering.
Favorite quote: “Life is never so bad that it can’t get worse” – Calvin & Hobbes.”
- Welcome days: Irfan has attended to a number of meetings and training activities organized by different academic organizations of the TECHNION to obtain information about the resources at his disposal as member of the University.
- Technical training courses: Irfan will take during the second semester of the academic year 3 graduate courses:
- Mechanical Properties of Engineering Materials.
- Finite Elements Analysis.
- Analytical Methods in Mechanical Engineering
“I was a bit nervous when I landed at Tel Aviv. It was my first time away from India. On the day of arrival, my PhD guide Prof. Osovski showed me the Technion and the Dynamic Fracture Laboratory. He helped me for the accommodation and initial settlements.
The next day, I met lots of people in the lab including Prof. Rittel – Who is a part of the Outcome Project. Everyone in the lab has been very helpful from getting an apartment to teaching me how to operate a heater.
Research is interesting, since experimentation, programming and modeling are included. One of the main constrain of the program is the 3 years of time limit. Prof. Osovski has given me an overall view of the PhD. Meanwhile, I am doing some courses as part of the program and carrying on research in parallel. Currently I am doing more of computational work and planning to get in to experiments in 2-3 weeks.
Main difference I felt at Technion is the gap between students and professors. In India, I admired and slightly feared professors. Most of the time I was too shy to ask questions. But here I didn’t see fear, professors and students are much alike friends.
Haifa is a hilly area and it is both good and bad at the same time. The place is beautiful and windy on the one hand and has challenging transportation on the other. Technion conducts trips inside Haifa for international students which has helped me to get to know history and places in Haifa. We have visited Haifa beach, art museums and different restaurants with expertise in specific items. And whenever there is time, Juan – my roommate and a candidate of the Outcome – and I go to some place and roam around. Most of the people can manage English here and that makes communication so much easier. I have started learning Hebrew as it would help to enjoy much more.
I have been here for more than a month now. It is thrilling and exciting at the same time and I am hoping for it to be the same in future.”
- Dynamic impact experiments of reverse tapered specimens made of PMMA with Hopkinson bar have been conducted to analyse the crack propagation and dynamic impact parameters such as stress intensity factor during fracture.
- To analyse the influence of interfaces in the domain during crack propagation, a reverse tapered specimen has been fabricated with different arrangements of inclusions. Specimens have been tested under static and dynamic crack propagation. This has been done with the collaboration of Prof. Stephan Rudykh and Viacheslav Slesarenko from the Dept. of Aerodynamics, Technion.
- A new method is developed and implemented in Matlab to evaluate stress intensity factor of specimen during crack initiation and propagation from the DIC of an experiment. Proposed method is verified with analytical and numerical data (FEA from Abaqus) and has been using on experimental data.
- SIF of the domain is calculated by mapping equivalent displacement fields. Fourier space is used for noise removal and surface fitting.
- Program is automated. Once the analysis started, program gives crack tip and corresponding SIF of each frame as output.
- Depending on the noise level in the DIC, multiple modes of fracture (both static and dynamic) could be analysed.
- This method is versatile and could be modified to use in different situations.
- Started to work on the numerical model to analyse the crack flow and interactions with inhomogeneities based on Prof. Cristian Dascalu’s two scale time dependent damage model.
