A method of calculating an impact resistance of a structure undergoing an impact with an impact surface is disclosed. The structure includes a first part bonded or secured to a second part, at least the first part comprising a material having a crush failure mode. The method comprises: a) determining that a finite element representing a portion of the first part is experiencing conditions which dictate that it will undergo the crush failure mode; b) determining a behaviour of the structure assuming it is subject to: i) an ongoing resistance force representing the crush failure mode of the element; and ii) a further force F acting on the first and second parts in a direction tending to separate them. |
