Impact Analysis of Bicycle Helmet

This example shows further results of a helmet impact analysis (courtesy of MET S.p.A., Italy). This time the head and helmet both have an initial speed of 5 m/s and side-impact a rigid anvil. This is one of several impact tests that MET uses to evaluate their new helmet designs. The results of another analysis compared with laboratory test results were presented some time ago.

The objective of the analysis is to ensure that the helmet provides adequate protection for the head. ADINA is used to check that the deceleration of the head does not exceed 250g, and that the stresses in the helmet do not exceed the capacity of the material.
