Program Timeline

In olden times, a motor vehicle was considered a luxury, But, the times have changed now. We could witness how drastically the numbers have increased. With the increase in vehicle numbers, the chances of accidents also increase. So, the makers must keep in mind the safety of the passengers and design vehicles which are crashworthy. The technical term coined for it is Crashworthiness. It is theoretically defined as the ability of a vehicle structure to protect the occupants. 

The safety standards of the vehicles are kept in mind. These reflect even before manufacturing the units.  The manufacturers start by designing the vehicles and using simulation, the crash tests are virtually conducted. This saves a lot of money and time. This reason has made the industry completely adapt to Crashworthiness analysis. The designers performing these simulations must have a full understanding of the vehicle design, factors responsible for accidents, the impact that is going to act on the passengers, and the safety standards that the market demands.

This program provides complete knowledge on safety regulation, designing and analyzing models, the mechanism behind a crash, and the skills required for a simulation engineer. This program offers several courses that individually deal with various topics that are mentioned above. These courses are accompanied by projects where you will get hands-on experience that will help you stand out from the crowd.
