This study performs finite element analyses ,of helmet impact, tests using LS-DYNA software. To compensate for lack of oblique ,impact, tests in ,helmet, standards, this article considers two oblique ,impact, tests. It measures linear accelerations, rotation accelerations, and ,impact, forces of the headform from ,helmet, test simulations.

The ,model, of the ,helmet, has been validated against both radial and oblique ,helmet impact, tests (Aare and Halldin, 2003). Three different impacts were tested (see Figure 1). For ,impact, 1 and 3, three different speeds (5,7 and 9m/s) where tested. For ,Impact, 2 an additional speed of 3m/s where also tested. For all three impacts and
