The Materials

Everything is subordinated to one goal: to absorb and distribute impact energy by means of programmed deformation structure. The programs used for simulations are also used in aerospace and the automotive industry. However, in aviation and even use similar composites products are not designed for survival in case of accidents. Accordingly, the materials are not required behavior for a given mechanical loading in different directions. In the auto industry, by contrast, used the structure of homogeneous materials subjected to preliminary molding of the plates. There are subordinated to one goal: to absorb and distribute impact energy by means of programmed deformation structure. Program, which is designed helmet, take into account the properties and mechanical properties of materials that to use.

They previously entered static parameters (elasticity and resistance to bending, compression and tear) and dynamic (impact). Virtual materials with specific properties allow the specified move from the aesthetic form three-dimensional model to a realistic model of the future of the helmet. The whole structure of a virtual helmet consists of small cells connected to each other and forming a grid. For virtual crash tests simulated conditions similar tests at a homologation. A virtual reality helmet worn by a virtual head with certain size and weight and then virtually beaten, forced to fall and drop them on a virtual anvil of a given shape. During these tests may be necessary to change the shape or size of the shell, and at this time designers and testers to work in close contact.
