MODELLING BEHAVIOUR OF MATERIALS DURING CRUSH FAILURE |
| 摘要 |
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; andii) a further force F acting on the first and second parts in a direction tending to separate them. |

1. A method of calculating an impact resistance of a structure undergoing an impact with an impact surface, the structure including 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 comprising:
a) determining that a finite element representing a portion of the first part is experiencing conditions which dictate that it will undergo said crush failure mode; b) determining a behaviour of said structure assuming it is subject to:
i) an ongoing resistance force representing said crush failure mode of said element; andii) a further force acting on said first and second parts in a direction tending to separate them. |
