The crash test simulation project appeared during the development of effective techniques for the procedural creation of various types of constraints with specified properties, as well as improving the skills of working with DOP solvers. It was a very interesting experience, I spent more than 200 hours on various experiments and created a large number of materials similar in physical properties to the materials that make up the car, such as hard and soft plastics, tempered glasses and laminated glasses, metal and metal alloys, fabrics and leather substitutes, and rubber. In the project, I used a Rigid Body solver, Pyro, and SOP solvers inside DOP, different types of constraints such as hard, soft, conetwist, spring and constrains dynamically changing types, UV-texturing, Mantra render.
The car model used in the project does not have power elements of the body, engine, door hinges and many other details that significantly affect the result of collisions in real tests. Therefore, I adjusted the deformation zone and the deformation force of metal elements, glass, rubber and plastic elements based on a large amount of personal knowledge about the mechanics and structure of the car and a large number of reference videos about crash tests that I viewed as part of this and the previous project.
Scene settings allow you to create constructs procedurally if you want to increase the number of geometry fragments.
