Background:

My research is concerned with the development of a die-set to control the microstructure and mechanical properties of a hot-formed part for automotive use. Traditional hot-forming produces a part that is fully martensitic, with very high strength and low ductility, which is very good for intrusion protection in the event of a collision. It has been suggested that by locally softening the material in specific areas, it is possible to improve the overall energy absorption, while still maintaining the structural integrity and intrusion protection.

The goal of this research is to produce a part with tailored mechanical properties, such that we can have very high strength in some areas, and other areas with increased ductility. This is achieved by controlling the die temperature, and therefore the cooling rate of the blank, at specific locations. This is all to be done in a single processing step without post-tempering or other heat treatments. The other side of the research is to model the forming process with LS-Dyna and use it to predict the microstructure and hardness after forming and quenching.

Research interests:

As the world strives for sustainability, it has become crucial for the automotive industry to improve vehicle emissions.  One way to improve the fuel efficiency of the car is to reduce the overall weight of the car.  Newly developed high strength aluminum alloys have attractive energy absorption properties and low density for implementation within automotive structural components.  As engineers, it is our responsibility to ensure that the new materials used to construct energy absorbing vehicle structure provide driver safety in the event of a crash.  My project will involve testing and modelling to evaluate the crashworthiness of high strength aluminum components under impact loading conditions.

I am a postdoctoral fellow at the University of Waterloo within the Forming and Crash lab. My research has been focused on the development and characterization of lightweight composite-metal hybrid material systems. I hold a MSc degree in structural engineering with particular interest in structural health monitoring and a BSc degree in Civil engineering from Shiraz University of Iran. I have completed my PhD at Dalhousie University within the Advanced Composite and Materials Engineering Lab. My PhD research was focused on development of a novel hybrid composite material for application in automotive industry. Throughout my PhD research, I introduced a newly developed 3D fiber metal laminate. I have conducted an extensive research (both experimentally and computationally) on the mechanical behaviour of the proposed material under static and impact loading conditions. In particular, the low velocity impact response of the material has been systematically investigated.

Research interests:

One of the major goals of the automotive industry is to reduce the total weight of its vehicles in order to reduce their fuel consumption and environmental impact. One way to achieve this goal is through using ultra high strength steels (UHSS) such as boron steel, which can be very lightweight. Traditional forming methods are not feasible for boron steel due to its high strength, so instead the hot stamping process is used. My research focuses on the tailored hot stamping process, where a portion of the die is heated to very high temperatures, while other portions are kept cool at room temperature. The advantage to such a process is that it can produce a part containing both stiff and ductile regions. This can be very useful in manufacturing rail components in cars, which need to withstand axial impact during collisions. My research aims to develop numerical models of the manufacturing and crash performance of an axial crush rail with tailored properties, and to perform experiments to verify the numerical model.

Background: 

I have always liked to do research on something that at its end, I could say I succeeded in helping industry to produce better goods for people. When I planned to start my B.Sc. project, my supervisor gave me a list of possible research topics I could work on. When he was giving me a summary of each of them, I got really interested in hot stamping process on sheet metal alloys since in addition to the compelling idea behind it, its practical usage in car industry would motivate me to step into this way. Hot stamping is a thermomechanical process for the fabrication of thinner components with higher strength, which leads to lowering vehicle weight and improving intrusion resistance in accidents. In my B.Sc. research, I investigated the mechanical properties of hot-stamped AISI 4140 steel sheets experimentally and developed this in my M.Sc. research by the prediction of the resultant microstructures after this process based on a coupled thermodynamics-kinetics modelling. I received both of my B.Sc. and M.Sc. degrees in materials engineering from the University of Tehran in Iran. In 2016, I achieved this chance to embark on my PhD research in the mechanical engineering department of the University of Waterloo under Prof. Worswick and Prof. Wells's supervision, two of the outstanding and knowledgeable researchers around the world, and have been working on the fracture characterization and modelling of the hot-stamped, tailor-welded blanks of different steels since then. It rarely happens to anyone whose main research topics in all the academic levels are the same, but I am so lucky to have always had hot stamping with me since I started academic research in university. We should wait to see if there is a separation between us at some point later!

  • The formability and crashworthiness of sheet metal alloys 
  • The finite element modelling of thermomechanical processes

My research is focused on improved vehicle lightweighting and crashworthiness through hot stamping of multi-alloy tailor-welded blanks (TWBs). The hot stamping process involves heating a steel blank to a high temperature before forming it between cooled dies, causing rapid cooling and the formation of ultra high strength material. Using multi-alloy TWBs, one material in the blank will harden when hot stamped while the other remains ductile, which is favourable for crash performance of an axial rail. The ductile region will collapse to absorb energy, while the ultra high strength region resists intrusion into the passenger compartment. My main research activities include experimental work using forming presses and a crash sled, and numerical simulation using LS-DYNA:

  • Forming of components from hot stamped TWBs and finite element simulation of the forming process
  • Evaluation of crashworthiness of these TWBs through dynamic crush experiments on a crash sled at up to 10 m/s, quasi-static crush experiments in a hydraulic frame at 0.5 mm/s, and finite element modeling of both experiments
  • Applying these hot stamped materials to the front S-rail of a production car. Initially this will be a numerical optimization study, then a simplified representative ‘demonstrator’ structure will be built and tested
