 · Crush injuries, however, are produced by static or quasi-static applied forces, which are defined as those that occur over a longer period of time (>200 ms) and are applied over a large area (as opposed to a point). These static forces squeeze or slowly deform an object, like the cranium, until it is crushed beneath the load.

 · The virtual quasi-static crushing tests are conducted where the model considers intra-ply and inter-ply failure initiation and damage evolution. The crushing behaviors of all triggered tubes are compared. From the predicted results, it is found that both the height of trigger and level of degradation have significant effects on the crushing .

 · The mean dynamic crushing loads are about 10% higher than the corresponding values in quasi-static tests and the obtained modes of deformation are generally the same as in the static tests. The increased force level at the beginning of the impact compared with a static test leads to a decay ratio between the measured dynamic and static mean .
